Cute and wholesome chapter that also moves things forward. Big fan. Uda is incredible and deserves the best.
For better or worse I don't think that'll turn bittersweet...
Neither do I. She kinda sells herself short and doubts herself, but Uda has a lot more of an effect on Riri than she realizes, and it's a matter of time before Riri connects the dots, in my opinion. I do feel like there'll need to be an "outside" intervention probably by Nagisa and Mashiro, once they do manage to pry themselves apart.
I also really like Uda not spilling the beans at this point, like you said, time and place for everything, and here I think the whole deal needs to stew for a bit more time. Also, question, why did you add quotation marks to Riri's name?
