For those asking about the novel, I bought the Korean books for Broken Ring from Ridibooks. This is how I read Korean novels. I rarely read translated versions unless they’re direct translations because I prefer to read what the author actually wrote. So far I have read about 20+ korean novels that all have manhwa versions.

I read all those books with translation apps. Take for example Reminiscent Adonis, The Great Wish, Ugly Duckling, False Confessions, Honey I’m Going on Strike and many others, I read them with translation app and even provided long summaries for some of them on Novelupdates. Many users on Novelupdates use translation apps to provide spoilers on that forum. However, I know not everyone likes to read MTL.
Ines doesn’t even realize she’s the one who influenced Carcel to be a clean freak. It was only featured in ep4 of the manhwa but Carcel took that lesson to heart ever since he was a kid and he’s obsessed with being clean. In the novel, even after sex, Ines is usually annoyed that he looks clean and put together while she looks like a mess. It’s mentioned a few times throughout the story to emphasize this is habitually a part of his character so he won’t sleep with Ines unless he’s clean. lol
Anyway, here in ch4 is where it all began when she washes his hands when they were kids:
