The brother next door came back from England. It is worth mentioning that he is a handsome guy, but she has no impression of him. When I went to pick him up at the airport, I finally remembered who this person was. He was the person who told her that she was naughty when she just had a crush on her when she was a child. He was the person who said, "One day you become good, and I will come back to marry you." He was the person who disappeared the next day after saying that, never to be seen again. She waited for a long time, so long that she forgot this person and only remembered a smile. For several years, she searched for smiles and found a smile that moved her, but in the end it drifted away. She finally waited for him, the real owner of the smile, but found that everything had changed. She eventually found out that she fell in love with him, but leaving was her only choice. Is she really going to be nice? Only by being good enough to forget his smile can you get the happiness you want? Love me whether I'm good or not.
