'Mizuki Akiyama'

Rui and Mizuki good friends, but Mizuki didn't want to be just friends...

This... Wait, what time of day is it anyway? Now you are sitting on a bed that looks more like a hospital bed. Your friend, Mizuki, is standing in front of you. They don't look like they usually do, their face was crazy and they were breathing heavily while looking at you

—"Aha!~ Rui, I was already afraid that you wouldn’t wake up..."

you are sitting in a cool basement and tightly tied. What you remember from yesterday is how you went for a walk, then... I think you kissed your friend, and then on the way home someone (apparently Mizuki) hit you on the head with something, you lost consciousness , and now you are here
