I Tried Becoming a Cupid, But Why do the Girls I Find Always Yanderes?

(Not my history!!!!) I am Tachibana Kyou, the likable, klutzy, perverted, dense character. Of course, my character traits do not stop there. I'm a genius who can become any character I put my mind to be—Acting talents perfect for a "mob", the crucial role that hooks up the main characters with the girls around them. Indeed, moving from school to school throughout my life to fulfill my passion, I have truly become the Modern Cupid! And for another year in this new high school, I decided to step up a level this time: Aim for a HAREM SHURABA, a situation that any guy would dream of! Things were surely going according to plan... And yet, why are the girls killing their love interests instead of confessing their love? Why are they looking at me so strangely? Why do they even know where I live?! ...WHO ON EARTH ARE THESE GIRLS?!
