The Billion-Dollar Girlfriend Project

The tycoon's son was obsessed with a common but cunning girl, the hottest girl in school. To counter this, the tycoon sought out a manipulative yet seemingly innocent woman, influencer Alexa, as their ideal daughter-in-law. If their son liked that type, they would find him a more powerful version. Alexa immediately took on the task of saving the lovestruck heir, as the offer was too generous. She then discovered her opponent was an old acquaintance, her own sister and former rival.
