Coercion is still rape. As the story is written now there the creator has never shown us any circumstances in which Nakyum could have been said to truly consent. Raping a character until he likes you is...not what consent looks like.
I wish persons would stop trying to make the story look nicer than it is. It's dark all the way through. Even if Seungho apologised for all he did it would still be a story about a servant "in love" with his abusive, rapist master. The end.
I know coercion is still rape if you give in out of fear for your safety/life, but this feels different to the other times because it is so brutal and the boy (NaKyum is a boy after all) is BEGGING him to stop and he slams him down hard and keeps going! Also, there were times when NaKyum did want it in previous chapters and even initiated. Those times were consensual/not rape.
The other times he was coerced or consented. THIS time is obvious rape! Irredeemable! I just can’t with this one.
