Broken! Why Is the Cold Heroine Really Moved?

[Book-traveling villain + system + single female protagonist + two-way running + easy and sweet pet] When Lin Chuan woke up, he transformed into a rich villain in the book who chased the heroine for three years and ended up with his family and everyone destroyed. In order to survive, he bound himself to an unreliable death-seeking system. The first mission is to make the heroine reject her hundredth confession. Lin Chuan looked affectionate on the surface, but prayed crazily in his heart: Reject me! Reject me quickly! Unexpectedly, Xu Qingyue, who had always been aloof, curled her eyes. "Okay, I promise you." Lin Chuan: "?" From then on, things went completely wrong. The system asked him to kiss her, but her face turned red when they kissed her for the first time; the system asked him to make breakfast, but she said nothing, but secretly set the alarm clock fifteen minutes early; another girl asked him to have dinner, but she was obviously jealous, but she still said seriously—— "I just remind you that we are still in the observation period." Lin Chuan always thought that he only accompanied her in this love relationship to survive. But gradually, he began to look forward to her blushing, got used to her harsh words, and became increasingly reluctant to end the so-called "observation period." Until one day, a strange childhood memory suddenly appeared. Why is the voice of the little girl who sat on the swing and asked him to shout "Please enjoy, princess" so similar to Xu Qingyue's? And that system lolita who always likes to call him "Brother Host"... Why would he remember a past that even he himself had forgotten?
