First I want to say , this is faaaar better than Totally Captivated.
It's s so dramatic like all average webtoons out there but I liked it + I don't get ppl who felt bad for Mr Yoon , he can't be secure with anyone else but his wife bcz of his crazy father and brother and ik his wife is crazy aggressive but she basically sacrifices everything for him so yeah don't feel sorry for him. Actually I felt bad for Mr Yoon wife the most , she doesn't want to married after she have a child without married but her father push her to married bcz she is getting older + he looks down at his daughter that's why he think a bastard son of a chairman is a good investment for him ...
After meeting him by force she prayed he treat her good bcz he looks decent but she slapped so hard by how cold he is and even choose a guy over her.
And I completely understand why yul become that crazy , he put an act but u can say he completely lost his confidence after his ex cheated on him so easily without give af about him afterwards. Just imagine how humiliated it was for him. He seems a guy who hate to do bad things , it's even mentioned he don't smoke or even drink, that's why he can't stand ppl who easily slept around, he is a strict righteous man with ocd but when it's comes to love ,he lose his sanity bcz he hate to felt insecure or lose , I totally understand him , how he can't trust ppl.
And I totally understand why Soohan looks like a pushover, he is craving starving for love , attention and affection but he never get it , he always begged for it and even betrayed by his partner in middle school too ,after used by him. He is so careful and obedient with his partners even in bed and so used to let them do whatever they want with him so they just love him a little more in return, he traumatized by how his partners treat him so poorly even hated himself for it. He never received half of what he give so he just dying for attention and a simple decent love , he basically cried after see ppl simply date in street.
From what I see , both Mr Yoon and Soohan are seems so similar personality wise, they need determined , strong minded and kinda aggressive/pushing partners to chase after them and done things for them that's why I'm satisfied by ending.
