Hmm. The seme and uke are both insane and manipulative.... haha they deserve each other so...

leave alone deserve they love each other they just want to spice things up and i feel sad for sunbae bcz he is having it worse than the mother at least she is not sleeping with the old seme

that's true. At least she's ignorantly bless. Not saying that its okay but at least she isn't hurt yet (since she doesn't know about them having sex behind her back)Tho I can't compare who has it worse...

if I were the mom and I found out that my boyfriend was using me as a tool to get to my son's asshole... I would feel betrayed. My boyfriend turn out to be an dick head and probably hurt that my son didn't trust me enough to say a dime. Or that he think I'll be happy with a man who is threaten my son to sleep with him.

And imagine the awkwardness if she ever found out. I mean, I wouldn't know what kinda expression to make to my son if I found out my boyfriend and son is having an affair behind my back... let alone the fact that I have to see him everyday. The mix of emotion twirling inside.

Actually, I'm not sure Kyunghee has even come out to her about his sexuality even. Sure, the lack of trust might hurt, but kyunghee's position is a lot more precarious than 'rich and powerful ceo blackmailing him for sex'... I don't think he's quite ready to admit to everything that led up to the situation quite yet because he cares so much for his mother and what she thinks of him.

But I agree that it's impossible to compare who would hurt more once things fall apart. I'm honestly a little inclined towards the mother because the pain would be twofold as her relationship to the old guy was very personal compared to seunbae, but who knows what impact this might have on seunbae's career and ability to trust others..
