Stepping on Roses, Volume 4 - Rinko Ueda
Rinko Ueda is the mangaka that brought us Tail of the Moon and as much as I liked that series, I think I love this one more. Rinko likes to show a defiant and impossible love due to the headstrong and loneliness of the main characters. It's always a tale of one part refusing to fall in love and the other party already half in love.

Hence the premise of this story. Sounds stereotypical but she does it so well.

I want Sumi to grow a bit more of a backbone and Soichiro to continue mellowing out. He's bossy and a bit of a jerk but he'll come around.

As for Komai? Wah!
