Lin Wan was the kind of girl who would say thank you three times in a row because her aunt gave her an extra spoonful of potatoes when serving food in the cafeteria. She thought "being liked" was the most important thing in the world. Until she was twenty-two years old, she received an unsigned letter with only one sentence: You have lost yourself. Later, it took her five years to pick up the lost self piece by piece. This is not a story about love, it is a story about a girl who decides to "see herself".
