After Su Chenchen becomes an heir to a demolition payout, she runs away to escape her greedy brother and sister-in-law. On the day she flees, she saves a man covered in blood. She never expects him to latch onto her, sharing her food, her drinks, and even her bed. One day, she steps out of the bathroom and finds him staring at her. Furious, she snaps, “Everyone thinks you're my boyfriend. You've been living off me for ages. Aren't you ashamed?” The man just stares at her blankly without saying a word. “Fine, I'll take the loss. I'll support you from now on. How have you stayed this clueless after all this time?” But she can't figure out how the clueless man she's been supporting for so long suddenly turned into a CEO worth hundreds of billions.
