Short Distance Love

The first time Daisuke had asked Kou to marry him, they were in kindergarten and he was rejected. But it's not like this has stopped him - not when Daisuke's been proposing every year for the past twenty years! Proposing and rejecting has happened so much between them that at this point, it almost feels less like something serious and more like a running joke. Has Daisuke ever thought about what he should do if ever Kou says yes?
