He keeps a diary named Keke and never leaves it anywhere except hidden in the small pouch of his satchel that he carries around with him all the time. He's been into Yongguk ever since the day he's met him at an unexpected moment and now he can't stop thinking about him.

Later on he notices that he feels Daehyun is the only person that he can connect with and starts getting closer to him.
