Ehm I'm seeing a lit of fights in the comments. ..
Is this manhwa worth reading?
Is there cheating? Angst?
Does the seme sleeps around or the uke?

From my understanding based on spoilers of novel readers. The seme is a psychopath so his love and empathy is to be extremely doubted. He sees sex as a dominating act to conquer weaker ones. He can't conquer taeui the uke so he gets intrigued. It seems like a obsession rather than a romantic story or passionate one.
On top of it all, seme sleeps with the guy whom uke is seeing while seme himself has little feelings for uke.
The glow up!! I fucking said the glow up!!!!
