Yandere. Noun. Wikipedia defines it as – “A Japanese term for a person who is initially very cheerful, kind, loving, caring, and gentle to someone (or at least innocent) they really, truly like and care about a lot until, their purely intense romantic love, admiration, and devotion becomes feisty, stubborn, bossy, and mentally destructive in nature, usually, but not always through either overprotectiveness, violence, brutality, or all three.”
