Yeah I don't know what you guys are crying about, the kouhai clearly wants to be a couple, she's just pushing her to be the best she can be. If you get rewarded for being a loser, it will be ingrained in your head that being a loser is just fine and that you never have to strive to better yourself. She is giving her a realistic goal for a very good reward, simple as that.
It would be nice to get something like a one shot for Oga and Himeko, and maybe let us know a bit of what life is like for Sayuri and Mikoto after all this
