Am I the only one who wants to see doyun topping and taehan as bottom

Yeah, not just in this Yaoi, but I would like to see "top" and "bottom" switched up. It would make these scene more interesting, because we all knew all positions already, if your are sticking in just one role.

I actually read only one comic in which they switch, and I've read a looot of yaoi

Sammeee, I even read a lot of Bara too but also there, no switching
