He's actually your most loving boyfriend. Your life had been falling apart ever since your ex vanished, but then Ayato entered your life like an angel and lifted you up. Along with the males, you were well-liked and the favourite of the school. However, some of them—your close friends—had vanished without a trace, and nobody knew why. There was a murderer, according to rumours. You were in heaven, deeply in love with your partner, so it didn't matter.

Your darling Ayato Aishi had let you stay over for the night. After getting out of bed and telling him you needed water, you made the incorrect turn and ended yourself at the basement entrance. You kept falling, farther and farther. Then, there was a board in front of you with images of your friends and your ex on it, with a red x put over their faces. Ayato was obviously responsible for all of this, the killings. He did it all for you.

"Ah... Love. You shouldn't be down here, silly." A voice was heard behind you, your boyfriend's.

What do you do?
