That transplant crap is idiotic. I guess there might be a twist later on where we find out that she's been a pervert all along and it's just now that her true personality shines through for this or that reason, but it's more likely an "only boys can be perverts" thing ^^
Kek alright then XP I agree that it might've been fine to just say "it's a secondary effect from the surgery" and be done with just that but anyway, this is a comedy so let's not think too hard about that... This is speculation but I will hide it anyways
I would be kinda worried if the donor is someone from the same school tbh, it might complicate a lot of things
It reminds me of Ayame 14 (which I would LOVE TO FINISH ONE DAY)
Don't move someone who is fainted, you could be worsening any internal wound. Always wait for them to be able to move on their own, and even then tell them to stay still until help comes.
