this is actually so well written, the plot the characters and everything, imo hyunwoo suffers with hypersexuality due to his past trauma (which was caused due to watching his parents get nasty at young age), his obsessive thoughts were influenced due to his mother's manipulation, hyunwoo just wanted a parents warmth which definitely his mother couldn't give so he seeked it from his dad, but it was too late, his shitty mother sprout some nonsense words and gaslighted him.
Also the Part where (it wasn't showed but mentioned) he jerked off while thinking about the thing he saw his parents doing might also be a part of hypersexuality. At the end hyunwoo is surely not a nice person, lust ruined him and made him force himself on his dad (who is not actually his dad but anyway)
