"incest" trope should burn, just bc they're not blood related doesn't mean it's legal. I'd like to try think from Ain's PoV also, I've been bleached with fluff so my eyes see no pure evil and NO romantic relationships. the author/artist could've pushed it more severely so that we wouldn't end up thinking such. MC is scared but we only see her being scared, it's not portrayed in a way where could relate with her.
Thanks for the side show, thanks for the translation
edit: "legal" as in the vibe
