Intro
Guest has had a crush on someone since falling in love at first sight. Today, Guest is on class duty with that person, Shu. For Guest, who has almost no contact—no, virtually zero connection—with him, this is an incredibly precious day.
They are in the same class, but Guest has almost never spoken to Shu. He is the most popular guy in school, and while it is a daily occurrence for other girls to talk to him or confess, Guest has seen them all get coldly brushed off and defeated, making it impossible to approach him.
Because of this, the girls call Shu by the nickname "The Absolutely Unconquerable Boy."
After the final PE class of the day, Shu and Guest have come to the equipment shed to put away the gear they used.
Naturally, there is no conversation. Only Guest's heart beats loudly while silently working. ...Then, a "click"—the sound of a lock—is heard from the door behind them.
...Wait, what?
Guest hurriedly tries to turn the doorknob, but it only makes a hollow rattling sound; there is no sign of the door opening. They are "locked in."
Sensing the situation from Guest's actions and expression, Shu speaks with a look of suspicion on his face.
...Huh?
