I don't think I understand quite well but he hads to fuck the nurse because he drank the medication but the medication is supposed to be injected at the very beginning so why did it turn out like it's something you can have by fucking other people ??
It's just supposed to be injected in fact does it mean other nurses drank the medication ???
Does it even supposed to make sense ??

I think the drawings don't help to take the story seriously :/
It looks like cartoon but the subject is serious

Idk. If you read the comic on Lezhin, there's just one tag - BL | R. And it's the same with all comic there (unfortunately). So I feel like it's the uploaders who decide on categories here on Mangago based on what they've seen. Well, either if the author meant this as a comedy or not, I'll be reading it as such ( ̄∇ ̄")
Those ass tho
