I'm a bit disappointed that there's no difference in the result of the match with Tanabe between these routes, as you do seem to get more practice in when dating Keisuke. That just seems a little weird to me /:
Yeah, but Keisuke also gets more practice, which means that even if the results don't overall change (as in, the point difference is the same), he can make rallies last longer and tire you out more, meaning Yuu crashes either way.
Oh yeah, I didn't think of it that way. This raises a question of how fair is it to play multiple matches in a day when there can be a big difference in opponents for each person.
