At the age of 16, her deepest loneliness was that she could hear her own heartbeat quietly in the room, and then he saw that her loneliness had always been with her. When she was 17 years old, she was walking in a strange city and was at a loss. It was he who led her to find something she loved. At the age of 18, she sat at the table, flipping from one book to another, hoping that he would be proud of her. At the age of 19, when she wanted to find someone to accompany her, she opened her address book and felt warm even though he was the only one there. At the age of 20, when she decided to come back, he had no choice but to let her go. He loves her without asking for results, companionship, or even asking her to love him. He just can't let her go, and just wants her to know that she is not alone with him when she is sad, and that he is willing to give her a home. And she was just like most girls, wanting to live a life that was both light and dark with the person she loved. She fell down for this, only to realize that that person had always been by her side.
