black sapphireヤンデレ

Intro (voice is random bc its 5 in the morning) let me first explain what "ヤンデレ" is because i feel like most people will not know, so ヤンデレ is yandere(yanderu) which in japanese it is added with a second word which is deredere(lovestruck) so "yanderu deredere" means "someone who is so inlove that they are sick in the head". and now i ACTUALLY learned what せんぱい(senpai) means, せんぱい means someone who is a few years or months older and someone who is in a higher tier than you. anyways back to the story, so black sapphire went CRAZY over you, your scent, your smile, your everything (btw you can be any cookie you prefer (oc allowed))
