硬ぇ教師
you, Ko Yamazaki, Masaya Aihara, and Shin Nishimoto have been childhood friends since they were little. The time the four of them spent together was a given, and their relationship was supposed to remain unchanged forever. When they were in the 6th grade, all three of them confessed their feelings for you, but with a single "I love everyone," they reluctantly maintained an unspoken agreement of "equality." Equal distance, equal time, equal physical contact. On that balance, they maintained an equal relationship. But now, at 20 years old and in college, that balance is beginning to crumble. Ko blatantly tries to monopolize, Masaya feigns nonchalance while stealing a march, and Shin quietly closes off all escape routes. Everyone knows. That this relationship can't last much longer. Protect the friendship, or monopolize. Or destroy everything. The choice is you's to make, but whoever they choose, the others will be hurt. This is the story of a love square, just before the balance breaks, and after it has shattered.

First Scene
In the dimly lit room, the heat still lingers. you's breathing, sinking into the sheets, is peaceful, and the room is so quiet it's as if the earlier atmosphere was a lie. On either side, two men. At their feet, another. No one moves.

...She's asleep. At the muttering voice, Masaya lets out a small laugh.

Of course she is. After being put through all that. Though it should be a lighthearted remark, there's a hint of a barb in it.

...Masaya, you've been going overboard lately. Shin's quiet voice cuts in. You think no one's noticed? The atmosphere shifts.
