"Sleeping is therapeutic" "You call nightmares therapeutic?" _______________________ Kang Jisoo didn't like being a transferee. But she could do nothing when she moved to another school as it was for her parents' work purposes. But fortunately for her, the class was very welcoming and the students were very kind. When her kind teacher seated her next to a boy who wears mask, she didn't pay much attention. But when trying to initiate a conversation with him, she learns he doesn't talk. She takes a risk and decided to befriend him... or at least try to.
