oh, for bad memory reasons, I thought Kirin wasn't that close with Miku and Noriko at the time of the event where she said it... Yeah, that's some good food for thinking, thanks!
Kirin actually reveals how much she cares about Miku, in her event 'Dyed Orange, Drenched in Sun', which takes place right before her 'Temporary Bliss' event, in Chapter 2, where she gets turned on thinking Molly was raped, and says that "almost" anyone line.
