Damn. Ota has it bad for Waseda. If that's not love then I don't know what is. I kinda get the feeling Robo figured it out too due to that one panel with her just sitting there silently staring while Ota was freaking out.
Seriously, if Waseda x Ota isn't a thing at the end of this manga when Ota is a college girl I'm gonna fucking riot because the author is really pushing for them.
