As someone who was not raised by their mother, I feel really uncomfortable reading this. For me, a mother is like a sanctity that you absolutely can't touch. Plus, I'm not attracted by women. And yet, the story is so good, the characters are all lovable, the internal dialogs are perfects!

It's weird, usually I don't have any problem to distinct reality from fiction, in truth I wasn't necessarily pointing at the incest matter. Even in real life I'm uncomfortable just seeing a hug between a mother and her daughter, or even an hand on their shoulders xD, what a nightmare when I was sleeping over friends house! So, I couldn't help but consider how great is this manga for being able to make me revive such a deep feeling trough fiction, it wasn't a bit negative, really. And thank you so much for conforting me, you're adorable! (づ ̄ ³ ̄)づ

scuze me Seiji, I don't want to be mean but maybe your sister would have (also) enjoyed her time in the palace from the start ( ̄∇ ̄")

Also *SPOILER!!!!*
She basically was telling him that she knew what was gonna happen, if they went together to the palace he was going to die, and if they ran away and hid they were going to be sold as slaves and that this was the only solution. She knew he tried to help her escape but it was really her who was protecting him by sending him to the palace alone.

we finally have some fluff
And, here I am, expecting "an easy target" to revive. My stupid scenarios :
1. Jisuh will cheat on Heejae just for pleasure, as a top. Heejae will be mad and will run away but he will come back begging Jisuh to take him. Except that Jisuh is now fed up with bottoming. Heejae will be forced to be the bottom for the rest of his life. AHAH
2. Jisuh is indeed a true pervert who intentionally play the shy M to seduce asshole men he chose with care while it's him who wants to have the control. All his partners ended up totally crazy. Heejae was one among many others.
just my wild imagination,
I love Jisuh, but I wan't him to be the bad guy for once!

I don't think you're entirely wrong with #2.
Jisuh is the type of guy who attracts very insecure and manipulative partners. A clingy insecure partner with a cautious withholding partner is a recipe for a fucked up and possibly abusive relationship.
I think their relationship will start to mirror the relationship that Jisuh had with the blue-haired ex-bf.

I would like it to be true! Except that in my scenario, Jisuh would be aware of that and using it as a weapon. But like other people who tend to attract manipulative assholes, here, Jisuh is not aware of his attitude and with the fact that he is repeating the same scheme. I wish he was a true bad guy.
seems like he found his motivation to join his dad's company
