I'm not sure why many people whines and complained about sexual assault's or non-con's scenes in every damn yaoi manga and manhwa. I mean this is just meant to be a story guys? Not every story need to cater to your taste and belief! If you don't like it just don't read. No need to flood the comment section. And btw for this story, it was a beastmen story. What do you expect from someone who have beast instinct? All flowery pooch story where everyone happy like that? Pfftt
At the beginning of the story Giyoon did said he could see ghost from time to time when he was younger so by pretending to not know or being unfazed might be because he actually used to it??? Or it's just a way for him to stop being scared of them???
