I’ve heard it could also be the situation , like Shin seeing Wolfgang in a strong sexy hunter settingwith the blood adding to that vibe
Shin always gets like that if you notice through the story, i think its because iirc the first time they did it was on the throne after wolfgang killed the previous king and he was all bloody because he slit his throat and cut off his head. So i think shin remembers/has flashbacks to that moment when he sees wolfgang all bloody lol
Oooo, so it’s associated to a sexy memory !
I was thinking this too!!
BLOOD KINK??! SHIN YOU FREAK?? okay i’m thinking maybe the blood in that world has some aphrodisiac effect or something to explain that
