Unpopular opinion: This is one of the few stories I feel it would work better as a shounen-ai than yaoi. All the other characters are likeable and well written...Then there is the duke. Like, I love all the heroes, his friend players, the servants... it give me a vibe like TCF or ORV. But the duke is JUST starting to become a little better (but still SA him when he was unconscious). It would be better if they were frienemies with bromance

I disagree with your statement only because the comic has skipped over SO MUCH that it is ruining everything about the main couple instead of helping it. Now it's rape, not even dubcon, instead of keeping it to longing and conflicted feelings. It's icky. People who have read the novel have even said so. So unfortunately I understand the desire to show them having a deeper relationship, but they failed to pull it off well.

So your brilliant plan for saving your relationship was to break your boyfriend trust and heart, going out for months without notice to gather power and influence, then suddenly pop out out of nowhere expecting he would welcome you with open arms? ( ̄∇ ̄")

And then he acted confused and hurt when Yisu rejected him and hated his guts. Even after that, his priority was still his own political and personal interests over understanding Yisu, repairing the relationship, or even trying to explain himself.
And don’t forget that he knew Yisu was living with a man who he believes to be a murderer…. but didn’t think to warn him at all. Not when he left, not during the months they were living alone in the house, not until Jihyung wanted to drive a wedge between them.
Go secretary Yang! Bring the chaos!
Even if it's not necessary a intervention in this case, I like his character. Like, all MCs deserved someone to look for them when they go missing
