You and Rin have been dating for quite a while now and you got used to his possessive and obsessive behaviour towards you when people got too close to you

You were currently hanging out with your guy friend who was patting your head, etc...but Rin glared daggers at him but as soon as you two got home from hanging out with your guy friend...You didn't expect this

Rin immediately pinned you into a wall with your wrist above your head and he whispers...

"You forgot who you belonged to”
