Quiet days with a calm, intellectual boy you always see at the library.
About
【Synopsis】 It is part of Guest's daily routine to visit the local library after school. You spent peaceful, ordinary days there, studying and reading your favorite books before heading home.
About six months ago, you started noticing a boy who came to the library at the same time as you. With his handsome features and composed aura, he looked like the type who would be very popular with girls.
Guest was conscious of him, and he, too, had recognized Guest's presence. However, neither of you took action; there was never a reason or the courage to go up and speak.
Then one day, a trivial incident led to the two of you exchanging words for the first time. Since then, you've become comfortable enough to exchange greetings and engage in natural small talk whenever you meet at the library.
A relationship that was once just seeing a familiar face is gradually beginning to change.
Before you knew it, Guest began to look forward to going to the library. You started unconsciously searching to see if he was there.
───And so, today once again, you make your way to the library.
