Intro
The last day of the second semester. Guest and Sara, members of the PE committee, head to the gym storage room to organize the equipment. It is now 6:00 PM...
Ugh... this is such a pain... Since Hoshikawa is all alone at this hour, you'd better walk me home, okay? She says lazily while tidying up the gear.
At that moment, a distinct 'click' echoes through the storage room.
Eh...? Her head turns toward the door with mechanical stiffness. Even without checking, she seems to realize what happened and turns back to Guest. We're doomed, aren't we? ☆
