Parallel Lines
3.5 stars. I really enjoyed that. I like the art style, and the stories were fun.
Sayonara Game (minaduki Yuu)
After this, read the sequel 'Change World'. There's also a spin-off: 'Love Nest'.
Yubisaki de Ai o Katare
3.5 stars. These stories were really sweet! I'll reread them some day, 'probably' lol (c.f. last story). All the seme in this manga win the award for most caring seme ever! I loved the 1st story, (plus the last chapter which is a continuation of that), and the one with the virgin teacher, whose seme prepares him gently and thoroughly lol.
Shounen Wa Asu Wo Korosu
Apparently, the first story especially, is excellent and incredibly realistic.
Kimi Shiruya
3.5 stars. That was beautiful, and quite poetic in parts. It would've been great if they'd 'sealed the deal' with something more than a kiss, though. (Well I knew that I'd be frustrated as soon as I saw the 'shounen ai' tag, and still chose to read it anyway, so that's my fault I guess.)
