Did she run away because she thinks the 'kiss' needs to be mutual? like it has to be very intimate like... u know. Both of em just need proper communication like heart to heart.
She literally just told her she has trouble making expressions all her life, and then she's like oh no she didn't make an expression. Like my girl did you just forget the last 30 seconds.
Idk to me the fact that she just kiss her so casually without any emotion is a reminder that it’s a one sided attraction (for now), although it’s part of the deal, I can understand why it would crush you to remember that fact at the exact moment you get your hopes up
Imo at least, you never know with Yuri mangas lol
