If we're talking about shoujo.
'Emperor and The Female Knight' has the most subtle romance development (as of now), but it's unfinished, so idk how it'll be in the future. Also, it has some decent 'realistic' points in terms of time period, which specifically revolves around war relations (as of now).
'Koroshi Ai' has also subtle romance and the title's mostly story driven so far, too.
'Otome Game no Hametsu Flag shika nai Akuyaku Reijou ni Tensei shite' is just pure braindead light comedy. You just read it (or you can watch it, there is an anime) for chuckles, romance in here is just kind of a part of a setting (much like in 'Zettai BL ni Naru Sekai VS Zettai BL ni Naritakunai Otoko' -- though it's BL).
'Chitra' is very much like so, and it has game stuff. 'Miss Not-So Sidekick', 'I Choose the Emperor Ending', 'The Stereotypical Life of a Reincarnated Lady' are also like that. Shut off your brain and enjoy all the mess.
'Spirit Fingers' is good overall, it delivers certain messages and has good comedy relief sections.
'The Flower That Was Bloomed by a Cloud' is good, but I don't really know where the plot is going, and I don't really like 'kingdom affairs' kind of thing, so I don't pay that much of an attention to it (it's going to be rather stupid and heavy I bet). But I enjoy the art, general flow of the story and its subtleties.
If you enjoy the shit-talking MC -- 'Beware of the Villainess!' is good for that.
'Bring The Love' has its interesting moments, the characters feel natural, I'm rather intrigued to where this is all going.
'Death is The Only Ending for The Villainess' has a survival theme with game stuff, it adresses certain issues which 'the tea duchess' deliberately hides or doesn't pay attention to (because it's inconvenient to the plot otherwise). Though you can pinpoint that MC is rather impulsive which ruins her 'let's act logically so I don't get killed right off the bat', but humans do be like that, and in such a situation, too. I just hope author won't make all this into a plot armor, so she will talk whatever freely with no consequences, assuming she's walking on the edge in this setting and all...
And with this theme 'Surviving as a Maid' has caught my attention simply because of a BL background. I hope the main group of people will stay gay, and not suddenly fall in love with her or something, unlike how it's done in every other maid title. Character growth is promising in this one.
'Exorcist and Devil-chan' is just pure fluff, no story. Though, beware of a huge age gap.
Speaking of age gaps -- 'Koi to Yobu Ni wa Kimochi Warui' is a decent shoujo title if you don't overthink and overcomplicate things.
'Milady Just Wants to Relax' has a romance tag, but from the translated chapters, it's not there yet. Though, I doubt there will be a story to tell, assuming it's a cooking title to top it off, but there is one huge thing to this title. FUR! God damn it, I love it!
Kind of a family title -- 'No Youna'. It brings up certain issues and tries to give its own honest answer to them. It doesn't feel like it's forced, it's on the 'natural' side.
'The Evil Lady's Hero' has decent smut, if you're looking for one. The story is forced and superficial though -- it's similar in that regard with the 'Living as the Tyrant's Older Sister'. But both are still enjoyable.
I think that's all from me.
