“There is no Uke more unreasonable and ridiculous than Hyesung from Love is an Illusion�...

idk man for me hyesung still takes the cake

Both came into their second gender unexpectedly. The difference is Doyun isn't taking advantage of his partner and continues to languish in embarrassment. I think they were slightly justified for confusion factor but now with the dust settling, there seems to be more communication with this couple.

At least Hyesung is a sugar baby, and makes his motivation clear. Doyun is all over the place, and is in constant panic mode.

Doyun is taking advantage, just not financially. Like okay, first time he got his heat is an accident. But when it kept repeating, like the least you can do is not be a butt to your sexual partner, right? He was pretty shameless asking taehan to play fiancé too. Anyway, I enjoy both mangas, just you gotta admit, the semes are way better than the ukes.

Wouldn't you be if suddenly the event you have grown tired of waiting for happened out of the blue? And worse, you end up continually having sex with a guy you work with and see everyday? I doubt he ever had a relationship before this and would be royally embarrassed at Taehan to the point of saying or doing anything to stay away from him until I could collect my thoughts.

I think he was so embarrassed and felt like he had no control so he was doing what he could to push Taehun away.
I will say there are times semes are totally creepy, though less and less in omegaverse. If Doyun continues down the "dumb" route, then this would get boring fast. (Hyesung should remain in the minority pool in terms of main character personality.) I think this may turn soon into more of what we want to see for this couple.

I get you. I really do. But that all went out of the window after Doyun started grumbling about Taehan acting hurt/angry for being rejected horribly, and then asking Taehan to pose as his fiancé. That’s just heartless, no? Like can you imagine? “I wouldn’t date you if you are the last person on earth, but hey, you can’t be mad. Also, come pretend to be my fiancé so I can move out of my parents’ house.”

I'm hoping this is the last time he acts so insane. The only reason I think Taehan is going along with it is because he has figured out Doyun is confused and perhaps wants to find out why. I mean, having someone whisper sweet words during sex only to do a one-eighty while sober certainly starts turning some gears. Some people act like that while drunk.
