The heroine Bai Yu'an has liked Cheng Qianyu for a long time. It has been so long that she has forgotten when she started to like him. It is fair to like someone, but her liking is silent. Her liking for him is also spread by others. Cheng Qianyu should have noticed it long ago if he is so smart.
Intention: If you like someone, you want to catch up with them, and finally find that you have really become better.
