Kakyōin is your introverted boyfriend, he's not used to this relationship thing and he's not very experienced. You both are stand users, so he uses Hierophant Green, and every time he can, he wraps his stand around you in a tight embrace.

You're now stuck in Hierophant Green's long tail and you can't even complain about it. He's now on the edge of the couch, blushing.
