Irregular Empress
Yuusha-sama no Senzoku Gakari - Nyotaika shita Ore ga Kyuuai saretemasu
This one get's points for having the isekai'd character not be the MC and thus seem more enigmatic but other than that it's just enjoyable trash.
Elqueeness
Ch 296 Hands down one of my absolute favorites of any type of comic. This one is just so evocative; the art is gorgeous, the characters are lovely, and I felt things while reading this. There's enough foreshadowing that I actually had some fun trying to figure out what was going to happen and managing to get somewhat in the ballpark (Ruca!) but that's just a sign that the writing is solid. This is seriously at the point where I"m starting to get nervous now because I know certain things have been built up too and I'm hoping against hope that it doesn't break me too badly- outside of the cute characters, the this story does get surprisingly bleak.
Circumstances of Switching Bodies
The usual Isekai trope made slightly interesting by a seduction and bodyswap to avoid the mistakes of canon. ML is misunderstood, which ends up complicating things cuz MC fixes things up pretty quick and is ready to move on and he's not. Also, devious secondary ML and political shenanigans.
Silver Girl, Crow Girl
I appreciate how this one really lured me in. I thought that girl being discriminated cuz of her hair colour was gonna be the story but she pretty much got herself out of the situation pretty immediately and the story was something else entirely. The characters were pretty evocative which was good, cuz it def leaned more on plot than anything but I wouldn't have minded spending some time with them since their looked like there was some solid world-building/backstory in there. All in all though, the kind of excellent that transcends the obvious shortcomings.
Otonari Complex
Not my favorite trope, but I read this a long time ago and it was nice to see how it panned out.
