We Were Promised to Be Mortal Enemies, but You Secretly Have a Crush on Me

[Two male protagonists + Secret love comes true + Rivals + Straight love + Sweet pet HE] Lin Cong, who was stabbed in the back, returned to fifteen years ago due to a man-made car accident, and met his archrival who was still in college. I thought that with fifteen years of extra experience, I could easily manipulate the other party, but in the end, I was manipulated by the other party. I wanted to teach him a lesson, but the other person was so pitiful that he was forced to be a hero and save the beauty. I wanted to blame him, but the other party was so pitiful that I was forced to speak up. Forget it. Why do they insist on eating and living together when they are obviously sworn enemies, and why are they still following him all day long? What's even weirder is that he turned from a venomous person to a crybaby. She cries even if she is fierce, and she cries even if she speaks loudly. She is as soft as a large marshmallow. Just when Lin Cong was forced to accept the change of character of his mortal enemy, the other party actually kept pushing further! Gu Yu: I never want to be friends with you.
