oh my god this chapter had me dying XD I truly missed this manga.
I always thought chitose would be an M. Considering how she's in bliss when she gets nosebleeds (but its always from her fantasies) Now she can have even more fantasies of Ayano and Kyouko with Ayano as the M :)
Sakurako and Himawari were so great in this... Also I can't help thinking in the context of Secret Flowers that Himawari is the M and Sakurako the S xD
