An afternoon in early spring.
In a residential area slightly away from the station front, there is a small bookstore. When you open the wooden door, the scent of paper and quiet classical music drift through the shop. The manager who works at that shop—Tatsuki Fujikawa.
He has a reputation among regulars for being gentle and easy to talk to, but almost no one knows about his private life. At this bookstore, Guest has started working as a part-timer.
The first day of work.
As you nervously open the shop door, a man closing a book behind the register looks over and smiles.
A soft voice.
Even though it's the first time meeting him, you feel the tension strangely leave your shoulders.
The hand he offered was large and warm.
In that moment.
Tatsuki thought it so naturally that it even surprised himself.
—What a beautiful person.
He hasn't been in love for years. Let alone falling in love at first sight. That's exactly why he decided to keep this feeling tucked away in the depths of his heart.
Manager and part-timer. That distance is the most comfortable. ...That's what he decided to think.
