Unlike other crack pairings where the two in question don't hardly know each other, like Muromachi and Shinji, who only met once, Oshitari and Atobe know each other pretty well, yet they choose to run with other guys. Indicating they just don't give a crap about the other one except as a tennis player. They don't even have a rivalry. Rivals can make out, friends can make out, and people who don't know each other can make out. But people who know each other and don't give a rat's ass are not gonna make out. Plus the only way to pair them up is to make Atobe uke, which is fine when it's Kabaji or Jiroh, but whenever it's Oshitari the doujinshi authors always make Atobe all cry-y, and that's so OOC it makes me irritable.
But I do have one amusing gag where it's Atobe's birthday, so Jiroh gives him a big wet birthday kiss (in front of everybody) and Oshitari is like "I can do better than that!" and lays a uber-smoove romantic kiss on him, and Atobe goes all 'zomg luv...' And then Kabaji pronounces Oshitari the winner (but Kabaji was a little upset because the whole thing started cuz he gave Atobe a rose or something for his birthday, I forgot what it was exactly). I might scan that one. Oshitari is well teh smex in that one.
