Maybe It's Courtship

Présentation

Every day, just like clockwork, Hirono Nanami hurries home—because if he doesn't, he just knows that annoying Godai would hunt him down and challenge him to a match again! As it turns out, Nanami can easily beat Godai in all kinds of sports except one, and Godai jumps on the chance...but, feeling bad that he's taken advantage of the one weakness Nanami has, Godai decides to settle things between them with something they've never tried before—by whipping out what, now!?
