After returning home, the bad news that her brother Roy (Simon Buret) ran away from home broke Lily's heart. For Roy's departure, the parents obviously do not want to talk more, Lily, who has a deep relationship with her brother, has to rely on her own strength to find traces of her brother. But looking for a person in the world is like looking for a needle in a haystack. In the process of finding a person, Lily's mental condition deteriorated rapidly and finally she was admitted to the hospital. One after another, Roy's letters saved Lily's life. Relying on her brother's letters, Lily gradually recovered, and finding her brother became the only meaningful thing in Lily's life. During this time, Lea's boyfriend Thomas (Julian Boiseler Julien Boisselier) came to Lily's side, and his company was like a warm spring breeze, soothing Lily's tired heart. Looking at the whole world, not only Lily, everyone is facing their own abyss.
