I feel unwell, so I head to the hospital alone to get myself checked. There, I find my wife, Luna Ackerman, accompanying the poor student I support financially, Levi Baker, for a health checkup.

Just last night, the very same woman held me intimately in bed and said we would be together forever in every lifetime.

I smile dejectedly and summon the system in my mind. "I choose to go back to my original world."

What Luna doesn't know is that I'm a transmigrator. I have accomplished my mission the moment I married her.

But now, I don't want her anymore.

"The host's request has been received. The passage back to the original world will be activated in five days."

At the same time, the screen at the hospital waiting area was showing Luna Ackerman's interview from the night before.

"Dr. Ackerman, congratulations on winning the most prestigious award in the medical field. Would you like to say a few words?"

The woman on the stage had long hair and a curvy figure. She accepted the trophy and looked at the audience. She carried an air that would make people keep their distance.

"The person I'm most grateful to is my husband, Noah Gosling."

She smiled when she mentioned my name, making her seem much gentler.

"If it weren't for my husband, I would've died in the rain ten years ago. I owe my life to him, so this trophy is meant for my husband, Noah."

The audience erupted into applause.

"Luna is the youngest woman to win the most prestigious award in the medical field. She's also devoted to her husband."

"I'm so jealous. I heard they were childhood sweethearts."

Luna, who was on the stage, heard those comments as well. She grinned wider and added, "Hence, I've bought Asteroid 27-9 with the prize money and named it after Noah. I want to take this opportunity to declare my love for my husband to the universe."

Luna's eyes sparkled as she spoke, but a bitter smile crossed my face.

Maybe her love for me was genuine, but it was also true that she had fallen in love with the student I had supported.

…

Ten years ago, I had transmigrated into this novel because I felt sorry for the villain, Luna Ackerman, and wanted to save her.

The 20-year-old me showed up during the darkest time of her life, when she was only 15 years old.

That year, she had witnessed her parents die in a car accident. All her relatives refused to take her in, and I was the one who took her home from the orphanage.

Luna was dependent on me. She never let me do any chores and gave me her entire paycheck after her first month of work. She only wanted to stay by my side as soon as she got off work.

During a car accident, she shielded me with her body without hesitation.

I, who was in the most dangerous passenger seat, was perfectly fine, but Luna stayed in the ICU for a week. She almost lost her hand and couldn't perform surgeries again.

Later, when she proposed to me, I ignored the system's advice and said yes.

I was willing to give up everything just to spend the rest of my life with Luna in the novel.

However, happy endings only existed in fairy tales because they didn't show the dull reality of married life.

A month ago, I had received a pink whip and a USB drive. It contained videos of Luna making out with another man.

I recognized Levi Baker immediately. He had once stayed in the same orphanage as Luna, and he was the underprivileged student I had supported.

I felt a stab in my chest, and the pain was excruciating.

Just then, my phone rang. Levi's provocative voice sounded from the other end of the line. "Noah, it's been a while. You must be surprised to hear from the student you once supported like this."

I remained silent, but he continued smugly, "Of course, there's a lot you don't know. Do you know how much Luna enjoyed herself when she was in bed with me? An old man like you can't satisfy her."

My fingers turned white from how tightly I gripped my phone. I felt as if I had been plunged into a cold, bottomless abyss.

After ending the call, I questioned the system through tears, "Why? Everything has been going so well between Luna and me, and she's been nice to me over the past ten years. Why would she cheat on me?"

I had supported Levi out of kindness, but why did he betray me?

"Maybe because she's the villain."

The system's cold voice was tinged with sympathy.

It told me that Luna was born evil. Even if I could guide her on her journey to becoming a doctor, I could never control the brutal nature within her.

She loved me and respected me, so she couldn't bring herself to hurt me. That was why she had to take it out on another man.

I felt a throbbing pain in my chest. Tears streamed down my face, dripping onto the back of my hand.

Right then, Luna pushed the door open and walked in.

Luna panicked when she saw me crying.

She crouched in front of me without even taking off her heels. Gently cupping my face, she asked, "Noah, why are you crying? Tell me what happened. I'll take care of it for you. It hurts me to see you cry like this."

Luna's concern seemed genuine. She held my face as if I were the most precious person in the world to her.

But the faint tobacco smell on her wafted through my nose, making me feel sick and disgusted.

It didn't matter. I would be gone in four days.

I didn't make it too obvious when I pushed Luna away. Then, I wiped my tears and replied, "I'm fine. I just watched an emotional drama."

Only then did Luna breathe a sigh of relief. She held me tightly and asked, "You dummy, what drama was it? I'll watch it with you next time."

I pursed my lips helplessly and asked, "Do you really want to watch it with me?"

"Of course," Luna replied without hesitation. "I want to do everything with you."

I said nonchalantly, "The story was about a really loving couple. The woman cheated on her husband, so he divorced her and left her forever. Do you—"

I fixed my gaze on Luna when I said that, for I wouldn't want to miss the slightest change in her expression.

The color drained from her face when she heard that the man had left his wife forever. She clasped a hand over my mouth and asked, "Why would you watch something like that? It'll mess with your head. Don't worry. I'll never leave you.

"I, Luna Ackerman, will love you forever. When you came into my world, you said you'd always be there for me when I needed you. I'll do the same for you, too."

I closed my eyes and said nothing.

Luna could tell that I wasn't in the mood, so she changed the subject. "Noah, cheer up. I'll take you out on a date. How about steak? I've been really busy at the hospital lately. It's been so long since we last went on a date."

She spoke sweetly to me like she always did.

My heart wrenched. I wondered if she was really busy at the hospital or busy hooking up with another guy.

When I got into the car, Luna helped me buckle the seatbelt. Since I hated driving, she would pick me up all the time.

I noticed that the "Noah's Seat" sticker she had placed on the passenger's seat had been touched, so I peeled it off without hesitation.

Luna's gaze dimmed instantly. "Noah, why—"

"I don't like the design of the sticker. Let's change it," I replied.

Upon hearing that, Luna breathed a sigh of relief. She beamed at me. "Okay, I'll listen to my hubby."

Messages kept coming in on Luna's phone while we were on our way to the restaurant. She picked her phone up and glanced at it. Her pupils contracted before she put the phone face down.

However, I had already seen the content from the reflection on the glass. It was a photo of Levi showing his abs in the bathroom.

"Noah, I suddenly feel like going to the Crasian restaurant we used to go to all the time. Let's go there tonight, okay?"

Before I could answer, she had already made a U-turn. She was in such a hurry that she forgot I didn't really take spicy food.

I only found out why Luna insisted on having Crasian cuisine after arriving at the restaurant. Her colleagues from the hospital were dining there, and Levi, who had sent me the pink whip, was present, too.

"Luna, now I know why you turned us down when we asked you to join us for the celebration. You've been spending time with a handsome guy," said one of her colleagues, who was drunk.

Luna's face darkened. "He's my husband. Apologize."

No one had expected Luna to react so seriously. They laughed and wanted to change the topic, but Luna said, "It's fine if you make things hard for me, but don't mess with my husband. That's where I draw the line."

Luna's drunk friend sobered up instantly and apologized to me.

I waved it off and told him it was fine, but deep down, I felt really awful.

Wasn't Luna the one giving me a hard time? What was she trying to do now?

As I was lost in thought, the group invited Luna to join them for the meal. But she turned them down right away, saying that she was on a date with me.

Then, they kept urging me to join them.

I glanced at Levi, who had been sitting silently in the innermost corner the entire time, and finally said, "Alright, I'll join you guys."

Luna seemed slightly reluctant. "Noah, don't mind them. We're supposed to be on a date."

In the end, both of us sat down at the table.

I wasn't interested in their conversation and quickly grew bored, so I decided to step out and get some fresh air.

Just as I stood up, Luna rose to her feet and asked in concern, "Noah, what do you need? I'll get it for you."

I shook my head. "It's fine. I'm just going to the restroom. I'll be right back."

Her colleagues laughed and said, "Noah, you're really lucky to have found someone as devoted and caring as Dr. Ackerman."

Luna looked at me, her gaze gentle. She confessed, "I'm the lucky one. I can't imagine what I'd do if Noah wasn't in my life."

Everyone seemed touched by what she said. Thinking how ironic everything was, I pursed my lips.

If Luna really loved me, then why would she cheat on me with another man?

…

I went into the restroom and saw Levi washing his hands at the sink. As soon as he spotted me, he sneered. "Noah, are you surprised to see how well I'm doing now?"

I said nothing.

He went on, "I don't think Luna actually loves you that much."

"Is that so?" I replied nonchalantly.

That seemed to set him off, and he suddenly slammed his hands against the counter. "You must think I've been living a miserable life all these years, don't you? Secretly making fun of me, right? You know what, I've found my biological parents, and I'm living a much better life than you."

He tugged his collar aside, revealing the hickey on his neck and a necklace. "Do you know what this is? Luna gave it to me as a token of our love. It's the same design as her ring."

The ring he had mentioned was our wedding ring. Luna had designed it herself, saying that it symbolized her unparalleled love for me.

But now, I had to share her love with someone else.

I caressed the ring on my ring finger, then removed it. Without hesitation, I tossed it into the trash can and left without looking back.

When I didn't return to the private room after a long time, Luna called me.

"I went home," I said. "Go ahead and have fun."

…

It had been barely ten minutes since I ended the call when Luna showed up right before me. She looked panicked.

"Noah, why didn't you ask me to leave with you?"

Before I could reply, her gaze dropped to my finger, which had nothing on it. Her voice was trembling as she asked, "Noah, where's your wedding ring?"

Seeing how worried she was, I felt the urge to ask her how she could love two people at the same time. She was asking about me, yet she was also in love with another man.

"I have no idea when I lost it. Maybe it fell off when I was sitting on the lawn just now."

Without giving it much thought, Luna dashed out of the house. "Noah, don't worry. I'll definitely find it."

It suddenly started drizzling, and Luna searched around the lawn frantically. Meanwhile, I stood by the floor-to-ceiling window and watched her coldly.

Luna's phone on the coffee table wouldn't stop ringing.

I answered the call, and Levi's deep voice rang out. "Luna, a new set of clothes has arrived today. Are you coming over tonight? I'll put them on and show you."

I replied apathetically, "I don't think she's free tonight. She's looking for the ring for me."

As soon as I finished speaking, I ended the call before Levi could say anything.

Just as I expected, Levi showed up at the villa 30 minutes later.

It was raining heavily. He ran in the rain and held Luna tightly, looking just like the male lead who had finally overcome all kinds of hardships in a romance drama.

Luna pried his hands off her forcefully. Suppressing her anger, she whispered, "What are you doing here? Leave! I told you not to show up in front of Noah. I won't go easy on you if he finds out about us!"

She shoved Levi to the ground, and he yelled, "I don't care! It kills me to see you like this. Is that so wrong? Besides, you're my woman. When are you going to divorce Noah and marry me?"

Luna rushed forward and clapped a hand over his mouth.

Suddenly, she seemed to have sensed something and turned around. Her eyes locked onto me, who stood in front of the second-floor window.
