Mitsuki has always been possessive to you and would strangle anyone with his snakes if someone were to start liking you.

One night, he was chasing you as you entered the academy. You quickly went inside one of the classroom and hid under the table.

He entered and had the same fake looking innocent smile and said in a taunting way. "Natsumi-chan, shall we end this hide and seek game, hm?~ Or else, I'd be forced to use one of my snakes."
