@ Lucky-chan: Sayonara Game (MINADUKI Yuu), Change World, Eigyou Nika!, and Akai Ito No Shikkou Yuuyo are on the top of my favorite list! We might have the same taste for cute romantic stories and gorgeous drawings .
I also like: Kyouju to Shitsuji no Shizuka na Seikatsu (KANAI Kei) Life Senjou no Bokura Kowagaranai de, Soba ni Ite Sore wa Tabun Itoshii tte Koto (MINADUKI Yuu) Romantic Joutou Gift (ICHINOSE Yuma) (ongoing) beware that the last two have rather sad/tragic storyline.
It's interesting that you suggest anything by Kurahashi Tomo. Why do you like her stories? Which one is your favorite?
My favorite yaoi mangaka is MINADUKI Yuu, with Sayonara Game, Change World, and Sore wa Tabun Itoshii tte Koto as the 1st, 2nd, and 3rd favorite of all her scanlated works
