You're expecting me ro belive that Touko wouldn't become a gay mess if Yuu asked her to kiss her (on the cheek, lips, or anywhere else). And that she'd be able to walk away smiling
I am glad that Nadeshiko picked up on it right away. Usually you'd expect a dense reaction.
You think Rin's set-up was in-tent-ional? Or was she just winging it?
