okay i kinda get the gist here : both siblings love each other to death but despises each other too? most likely because of their second half. the sister wants freedom and is jealous of her brother. but the girl just doesnt like the boy? she just hangs onto his affections for validation? not sure really.. the brothee loves thw sisster to death and wouldnt be able to live without her, and is super possessive of her, wants to lock her up beacuse of this. but thw boy inside him hates her for abandoning him for her brother who tortured her and also treated him like an animal. thats why everytime sister calls him johan cuz hes in brothers body hes rlly angry. but ofc he loves her so much boy runs back to girl everytime she shows interest in him. both brother and boy worships girl and sister. I LOVE LOVE LOVE THIS MANGA PLS GIVE IT A READ
