What made him change? Lin Zhu also didn't know what made him want to change himself after so many years he became a scoundrel who only cared about his feelings without caring about anyone's feelings.
He only knew that he felt bad when he saw Xiao Mimi looking terrified in front of him, and that was why he hesitantly apologized in front of the chubby girl. No one forced him to apologize, and no one gave him any kind of pressure, but he still apologized to the girl after he realized the childish mistake he made years ago.
He tried to appear sincere in front of the girl because he really wanted to correct his past mistakes, but instead of getting a response from the girl, he got a question from his best friend.
