Yukimura-sensei To Kei-kun
By the mangaka of 'Given'! About abandonment issues and feelings of vulnerability.
Yuuhi ni Fureru Sono Mae ni
The sex is mentioned/implied, but not shown. Sounds quite poetic and slow-paced.
Only the Ring Finger Knows
I tend to stay away from 'just' shounen ai, but this looks really sweet, (in a relatively realistic way), plus it looks fun, and the [presumably] seme looks hot. It's really long, though!
Crown Craze
This is tagged as yaoi, but it definitely isn't. Wasted my time on this typical shounen ai, where everything's just like shoujo but with 2 guys. Boring and overly melodramatic at the same time. Hopelessly romantic and unrealistic and 'fleur bleue' *pukes*. Liked the art style, though.
Saiyaku Wa Boku O Suki Sugiru
Only shounen ai, and pretty long. However, the storyline seems interesting, and apparently there's some really nice kissing action, (though nothing more).
Haikyuu!! - Kokoro Control (Doujinshi)
This is so beautiful! It captures the emotions so well, that I think the mangaka must have experienced something similar firsthand. For me it was a lovely trip down memory lane, revisiting my own, similar experiences! Anyhow, I loved it, and I'm now off to read all of her other manga...
