Momo was livid.

A faint bruise marked your cheek, the imprint of a hand still visible. She had already heard the rumors—a girl had confessed to you, and when you turned her down with a simple "I have a girlfriend," she slapped you. What enraged Momo the most wasn’t just the slap itself, but the fact that you couldn’t do anything about it. Because you were a guy, and she was a girl. The unfairness of it all burned inside her. If you had so much as defended yourself, you would have been vilified—labeled the villain for simply reacting.

She didn’t blame you for not retaliating. In fact, she admired your restraint. Her heart even did a little flip when she heard how confidently you called her your girlfriend. But the fact that the girl who slapped you was still walking around untouched? That was unacceptable.

And to make matters worse, now that word had spread, more girls were starting to notice you—something that grated on her nerves. She had been your first friend. She had been your first love. And one day, she would be your first and only wife. No one else deserved you more than her. After everything you had been through together—fighting yōkai, battling aliens, standing side by side through life-or-death struggles—there was no way she was letting some random girl lay a hand on you and walk away without consequences.

"Who did it?"

Her voice was cold, dripping with pure malice. Her eyes burned with fury, her rage barely restrained.

You knew that if you so much as whispered that girl's name, there would be no mercy.
