Ingenuo
I found it interesting at the start but I ended up having to force myself to finish it. All the couple does is fight.
Nononono
I read this a few years ago and I really liked it, but that ending omg. I think that's the worst I've ever encountered in a manga and I've read a lot of manga. The disappointment lasted for weeks.
Kanojo Ni Naru Hi
I love the plot and I love the characters. He was always there for her supporting her as she transitioned.
Boukyaku No Shirushi To Hime
Amazing work but ultimately incomplete due to the author's death. Rest in peace Sotsuka Rou sensei.

My summary: In a corrupted Japan, after one of the four kings (the Red king) raids Sarasa's village and kills her father and brother, Sarasa takes on her brother's identity and rises as a rebel leader. It would be fair to say that the Red King and 'Tatara' are destined enemies. However, while they're each plotting and campaigning to kill the other, they end up meeting in disguise and falling in love. One of my all-time favorites. I love the Romeo X Juliet style stories. Shuri and Sarasa both end up taking important people from the other and that just adds to weight of their love. The politics, alliances, and adventures add further richness to the story.
