For non anime fans- Yandere is extremely possessive girls In an open world MMORPG game called Stellaris Fantasia Online, me and my partner we're rising to the top, killing other players, farming loots and so on.... But, yes, this partner of mine won't let me play with others.... even with my friends why? because she's a Yandere.... Its so irritable that I unfollowed her.... well that decision hurts me too, since she might turns out to be a hot onee-san (older woman) But as soon as I attend the class, my homeroom teacher is in bad mood... Why?? Just read the title....
