Im not willing to go over every single scene here so i'll take one from the side stories.
1. https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-13/ "S-stop!" Hyesung is hesistant because he doesnt want to do it in public for fear of being caught.
2. https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-35/ "No!! Dont do it!!" Hyesung is expressing the fact that he does not want to have intercourse right now.

https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-50/ https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-51/ "Hurry...please" Dojin ignored what Hyesung said and didnt acknowledge his lack of consent. This is categorised as marital rape.
Another thing to note, according to the FRIES of consent. For something to be consensual it has Freely given, Reversable, Informed, Enthusiastic and Specific (to read more on it look at my bio and scroll a little. Well this scene doesnt even tick half the boxes:
1. Not freely given https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-11/ https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-15/ Both these scenes are coercive "It'll only take a second" = It will be fast just let me do it + "i wouldn't be doing this if it weren't for you anyway" = why are you complaining this is your fault. It makes Hyesung feel like he has to give Dojin what he wants despite his refusal.
2. The consent wasnt Reversable because well, it wasnt there.
3. Unenthusiastic https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-24/ https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-28/ https://www.mangago.zone/read-manga/love_is_an_illusion/uu/br_chapter-150385/pg-30/ Hyesung felt obligated to give Dojin some sort of sexual relief and at first dojin aknowleged it but then he uses the fact the Hyesung was 'soaking wet' to indicate that he was turned on. When, in fact, this manhwa has made it clear that it is an uncontrollable physiological reaction. Like a boner.
Thank you for reading this far, i hope your confusion on consent cleared up. I reccomend this video if you ever feel sorta confused again. https://www.youtube.com/watch?v=NLKWEUhOHss

The issue here isnt his desire but the fact that it was unconsensual, you are severely misinterpreting everything i say and making up your own idespas without even realissing it. Im not going to be trying to convince you anymore. Read my first repky to you again if you want to and actually look through it. You dont have t though shitt

1 . https://iweb16.mangapicgallery.com/r/newpiclink/love_is_an_illusion/150385/150385_27817108.jpg he didnt want it cause he was afraid of dojin being on the news not cause he didnt want it
2 https://iweb16.mangapicgallery.com/r/newpiclink/love_is_an_illusion/150385/150385_27817139.jpg he obviously wants it look at him melting
3 https://iweb17.mangapicgallery.com/r/newpiclink/love_is_an_illusion/157817/157817_28670891.jpg he treats dojin like trash even though he loves hyesung to the moon and back.
dont try to bring rape when there was none
This is so funny to me cause outside of sex (Initiated by hyesung i am not refering to all those rapey scenes) Hyesung seems to really dislike Dojin. This goofball is so prideful too, hes my favourite character + Chowon's baby + Byul i like him a lot.
