(Every time I try to write this part, it becomes long winded.)
Basically, this is not how a relationship like this works in real life and I'm annoyed that Ryuu pushes Koharu even though she is obviously not comfortable and not enjoying it.
Its still one of the better harems and more believable than those harems with milquetoast protagonists who just go with the flow. Ryuu is one of the best harem protags Ive seen. Not a self insert, flawed as hell, quirky, does what he wants instead of letting the girls drag him around.
A woman who doesn't want sex has no business getting married. Sex is pretty much central to marriage, otherwise, just be pals. She took his money and she agreed to the marriage. He gave up fortune to get her out of debt and lives in a crap house with a crap job. For her. He kept up his end. I see her as the problem, frankly.
Neither Sangwoo or Yoonbum are innocent in this, but man, Sangwoo is doing everything in his power to make Yoonbum think that he might actually have feelings for him. It's kinda sad when you see it happening and you can't really do anything about it. The constant give and take he does is specifically to make Yoonbum think things may change when they never will.
And the people who are cheering Jieun's situation, shame. Sangwoo set her up to be in this situation. He was charismatic and charming, he knows all the right things to do and say to make woman fall for his trap. This doesn't look good for her, but part of me is hoping she manages to either get herself out of this or con her way into the same situation that Yoobum is in.
Then again, this is a psychological thriller, so, I won't keep my hopes up.
