Since when did yashiro have an earring? Or did I just never notice until now?

i think the extra chapter is set in an au (alternate universe) setting :>

I was about to say the exact same thing but already saw this lol. I was like, "am i hallucinating or is that an earring? or has it always been there and i'm just not paying attention because yashiro's face is too beautiful to notice the fucking earring?"
