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!
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.
Ok, beyond the incredible annoying new plot, I'm so interested in the OG ML and FL! He seems like a dickhead, we know the novel was written by an unreliable narrator (Veronica) but still he doesn't seem like someone she would fall in love with. And Veronica herself is sus too! I wonder what stakes she has to be asking the FL to stand up against her MIL. ( ̄へ ̄)
The fact that Onodera hasn't confess BLOWS my mind, this was one of my first yaois! It's like the BL version of One piece.
