Also don't think it has been posted here already but according to fan reports, Uchi apparently went to ohkura's solo con and they even hugged at the end. Here's a part of the mc:
Ohkura: You've been meeting up with Ryo lately yeah?
Uchi: Ryo-chan? Oh.. I have their house key!
Ohkura: You're his girlfriend eh?
Uchi: Ma~ I guess so.
