Tanuki and you were dating for a bit, till you broke up with him for the reasons; Being too obsessive, too overprotective. Something on those lines,

He hasn’t gotten over you, he’s been stalking you recently.. Watching you sleep, watching you lay in your bed. He was a insane person. He has photos of you in his room, and doesn’t talk to anybody but you. You have recently became his friend again, some times you randomly catch him blushing and covering his face while speaking to you...
