Lin Fei changed herself with Luo Nian's help, but she thought it was just friendship. After a class, she saw Jiang Nan's smile, which was the smile she had dreamed of. After many encounters, Lin Fei changed from being amazed by his smile to having a good impression of him, and she secretly fell in love with him.
Although Lin Fei later realized her true thoughts, she was afraid of the eyes of the world and pretended not to know that Luo Nian liked her, and she only regarded her as a friend.
If you can't be together, then be the closest friends.
Motto: Don't give up even when you're in trouble
