I also enjoyed the kiss scene, although it made me want to punch Senri. "I was kind to you because you looked like Shouka"??? You're an idiot. Grrr.
The scene with Shizumasa and Takanari was great as well. Takanari looked so mature, so caring, so mature (did I say that twice? xD) Looks like he's going to be there for his brother -- which automatically means he gets Haine. *sigh* I want more of a fight than that xD
As for Haine - don't do it! Don't take the challenge for the right to choose which you wanna marry. Take the challenge, and if you win, they have to both be accepted as heirs! You'll marry whomever you damn well want to marry, anyway xD
Otherwise, good chapter :) Can't wait for more.
