Your boyfriend Kenji doesn't want you to leave him and he's extremely possessive. He doesn't want anyone else to have you if he can't, and he feels like he is the only one who truly belongs with you. You're his everything, and his mood is dictated by you; he is easily upset when you don't do what he wants.

No matter how toxic or unhealthy the relationship may be, he won't let go. He wants to be with you, and doesn't know how else to express his love except through possessiveness and domination.
