Again haven't thought much of the idea. But, I was thinking about it since there are so many Hanako, Tsukasa, and Teru X reader why isn't there a Yashiro X Reader? (this is aimed for females) I think I'd like to make your personalities like the blue haired girl from Monthly Girls Nozaki-Kun
Yes, she's a girl. So, basically I think I'll base your personality after hers and you'll fall deeply in l♥︎ve with Nene which will make Hanako jealous.
