Devil in Winter is sooooo good! I would recommend it for the "devil" theme, as well as wicked and the wallflower, maybe even the duchess deal. Keep in mind, I don't think the heros are quite as manipulative as this ML but they really are morally ambiguous and very seductive.
Also good historicals are marrying winterborne and dreaming of you.
This writing and plot reminds me of more typical western historical romance books, he really feels like the devil trope from stories like "Devil in Winter". The point is that those books really go to town on the redemption for the hero, which is something that I have not really seen in manwha. Needless to say I'm so exited for more!
