Isekai BL + omegaverse???? I'm sat.
Anyway, I love when uke is like normal with common sense among all the crazy characters (especially crazy seme lol). It's such a nice contrast. I just love this dynamic.
Btw, our boy got isekai-ed to his sister's BL world. It's omegaverse magic school theme. However, our boy doesn't have a known secondary gender yet cus his sis was like we'll give you one when we found you a lover lmfao.
