Finally gave up trying to scan the search pages for some manga I remember starting but never finishing. Especially since many details have faded with time. So! I'm looking for 3 manga (obviously) and if anyone can help me find any of them, that'd be appreciated. I dont recall if they were good or bad, but its killing me that I can't remember them

First one: (which details I remember best) it's about a "king" in that she doesnt know that but her and several other incarnations of kings of her country can "meet" in a room, all from varying times, both future incarnations and past ones. In present day, though, I believe her brothers are fighting for the throne. She gets along with a least one brother.

Second one: (of which I have vague details but less than the first) a girl gets transported or reincarnated into another world where she is given a "mission" to woo some important person. She fails the first time and gets executed. The next time she finds out about a pocket room/dimension to work on her appearance and whatnot. She is a maid at the start and I believe she has a fairy companion/assistant and that she was bullied before she arrived.

Third one: (which I barely remember at all) I believe the protagonist is transported to another world. There are definitely bird people, with their heads being the bird part. I think theres a pair of siblings (twins?) and one does (less sure about the death part). This story is a over a decade old and has been released in America officially as I read it before I got into scanlations. Had a very Alice in wonderland feel in the sense that everything is strange and novel to both us and the MC.

Thank you for any and all answers. If I should split this into multiple posts, let me know.

The second one sounds like Goddess Creation System.

You're lucky I keep things I stopped reading still listed lol.

First one: Okoborehime to Entaku no Kishi
Sadly it's discontinued. So it just stops after 17 chapters...

in need of romance?
uncommon, sad, sweet

Yes those both seem right! Especially the one with Leticia, though it sucks that it got cancelled =(
