They Say I Was Born a King's Daughter
First half is good but quality drops pretty badly afterwards
Okobore Hime to Entaku no Kishi
It's a very good and original story. Nothing like it out there specially when it comes to how she's connected with the incarnations from her past AND future. Unfortunately, it's discontinued (ends in chapter 17). If you want to finish the story though, this manga is based on a novel that you can try to look up and read.
Sand and Song of the Seas
It's a Ouke no Monshou with a more serious tone. Both heroines time travel to the past and fall in love for pharaohs. However, Ouke no Monshou is more cliched and cute while this is sadder and more painful to read (happy ending btw). I did not like how the main characters did not get enough time together and the ending could have been much better. Therefore, 4 stars.
Yuki wa Jigoku ni Ochiru no Ka
Overall I thought it was messy. I wasn't able to take the plot seriously and the characters were all lacking. At the start I thought it was interesting but I don't like how the relationships between the characters developed. It seemed a little too complex than necessary. The one thing I did love however was the ending. The last chapter of this manga leaves you in a cliffhanger but things are perfectly wrapped up in the Kaichou wa Maid-sama X Yuki wa Jigoku ni Ochiru no ka crossover special which is the real ending.
Futaribocchi no Ever After
Even for a one shot, it's a lil bland
Suddenly Became a Princess One Day
Hope it has an extra story cause that ending has as many holes as swiss cheese. 4 stars cause of that
Soul Kiss
