StriderTuna said: He's done this pairing before, but not with Yuuka as the aggressor.
Mattari seems to jump around a lot with Komachi x Yuuka. Sometimes Komachi acts reluctant to Yuuka's advances while other she seems to enjoy Yuuka's company while the latter don't know what to make of herself.
rune_reaper said: Hardly unlikely. Both have a signature flower, they both appear in the same game (to my knowledge one after the other), and they're cute.
And can any Touhou pairing be considered unlikely?
