Man, this one was awesome. It has been years since I read it, and I still remember how good it was. Wasn't it axed? It ended way too fast.
It's been 1-2 years since I've read these so I don't remember them too clearly, but I've rated these 10/10: The Antagonist's Pet, What's Wrong With You, Duke?, Observing Elena Evoy
These are also 10/10 with angst and more dark themes (where romance isn't the main focus but very good stories) Concubine Walkthrough, The Knight And Her Emperor, Lethal Romance.
Disclaimer, The Knight And Her Emperor is very dark in the beginning as it's a more realistic depiction of women during wartime, so you see where I'm going with that.
Bonus good romcom with "unhinged" MCs: Beware The Villainess, Miss Not-so Sidekick
