The Day I Become a Butterfly
Chapters 3 & 4 are shoujo. The rest are shounen ai.
Shimanami Tasogare
By the mangaka who created 'Nabari no Ô'. They themself are x-gender, (is that the same as agender?), and asexual, apparently, so know first-hand both the internal struggles and the societal pressures faced by such rl people in Japan. Note: This is NOT yaoi. It does have a little shounen ai, but the focus is on the struggles of LGBT+ people, rather than their romantic/sexual relationships. It was published in a seinen magazine, hence it's not meant to be fujoshi fapping material lol. I.e. Read this for a realistic and sensitive portrayal of LGBT+ people in Japan. After this, read something by Hagio Moto, whose works inspire this mangaka.

3.5 stars. This was quite good, though I can't really say I LIKED it, cause it's a bit painful to read due to the love triangle. I would've liked them to have ended up as a 3some, or at least tried 3p together once. Although, they're probably all too jealous for that to work out. Have just seen that there's a Flowers dj by the same mangaka, so I'm going to check that out...

3.5 stars. I was hoping for it to become a 3some, or at least for them to try 3p once, but in fact, I'm glad for Nanno that he realised what he really wanted, and was strong enough to walk away.
