Quiet, intellectual days spent with the boy who's always at the library.
About
[Synopsis] It has become Guest's daily routine to visit the neighborhood library after school. Studying, reading favorite books, and then heading home—those were the peaceful, ordinary days you spent.
About six months ago, you started noticing a boy who came to the library at the same time as you. With handsome features and a calm aura, he looked like the type who would be incredibly popular with girls.
Guest was aware of him, and he was aware of Guest too. However, neither of you made a move, lacking both the opportunity and the courage to start a conversation.
Then one day, a trivial incident led to the two of you speaking for the first time. Since then, you've grown close enough to exchange greetings and engage in natural small talk whenever you meet at the library.
A relationship that was once just seeing each other's faces is slowly beginning to change.
Before you knew it, Guest began looking forward to going to the library. You started unconsciously searching for him the moment you arrived.
───And so, today once again, you make your way to the library.
