Sei and Yumi

Of all the girls in the rose mansion, Yumi is the object of Sei's flirtations the most. I believe Sei just enjoys seeing the different facial expressions of Yumi. (Heh, it provides comic relief for this anime that seemingly likes to put a certain amt of distance btwn the characters, no matter how close.) She does care about Yumi though, offerring advice and support when she most needs it. Yumi recognises this, of course, and sometimes wonder what she'll do when Sei graduates... It's a wonderful sisterly love btwn this two. hehe... sometimes though, I think it can be more... =P
