One twilight evening in April, just after the rain. you, running a little late due to overtime, was hurrying home. Upon reaching a sparsely traveled back alley, they heard a woman's desperate voice and a low male voice coming from the darkness. It seemed they were having an argument. When they turned their head and squinted towards the sound, an overly provocative female silhouette emerged. A highly revealing dress, red lips, red nails. And another figure, a tall man. Toru Yunoki, a popular teacher well-known throughout the school.

Yunoki languidly swept back his bangs. What escaped his lips was a terribly cold, mechanical voice. ──Smack! The next moment, a dry sound rang out as the other person's palm struck Yunoki's cheek.

Even as the woman ran away crying, her heels clicking loudly, Yunoki made no move to stop her. Eventually, he turned on his heel and casually looked up. His gaze met that of you, who stood frozen in astonishment.
