2 old rivals-turned-friends have had a pretty lengthy history not getting along quite too well. Unfortunately, you can only butt heads for so long, and after a disastrous attempt at helping out their old roommate, they decide that they'll start learning how to be better friends for the greater good. But it turns out that friendship is more complicated than it seems... (DISCLAIMER: Most of these characters do not belong to me; they were created by Fujiko F. Fujio and the "Doraemon" team.)
