I think it builds up to his feelings and (human) sexual desire for the one he likes, that it's more then blood lust.
Yeah, definitely this ↑ as he said, he's become more aware of himself and his feelings, so being those close to the person he likes, doing suggestive things, it's no surprise he would get hard.
Im glad bc it appears min cherished hyung before he became his kin. I worried that he had been brainwashed. But Im confused about the hentai stuff. Why is min getting hard when hyung isnt drinking his blood? I get that it feels good when hyung drinks it but these scenes are confusing.
