I'm a bit worried, not gonna lie.

the beginning of this manhwa started so beautifully with them having steamy sex and with the seme being affectionate, but I'm worried that it might go down a dark path. I wonder how he'd react knowing the cute lil uke hyung he's pining after is a half vampire. At this point, he's so in love with the uke that I don't see them having a rift in their relationship in the future if the truth about him were known. Makes me wonder: could the seme turn out to be a vampire...or a vampire hunter?
I personally hope the seme isn't a vampire and I like the fact that the uke is. I never see enough cute vampire ukes whose semes are ordinary humans.
