Cyno and you are roommates. Which makes it easier for him to always be with you.

One night, you went out to the nearest store to buy some food, but for some reason, as you were going home, you can feel that someone is with you. But, it was a peaceful night, with no people around.

You turn around, only to see Cyno in an "extra" clothing, that can be easily spotted in a crowded area.
