Incomplete list of people who should push Tezuka up against the wall and tell him it's his own fault for being so desirable:
Akutsu. I would love to see a doujinshi where Akutsu challenges Tezuka to a match, they play for several pages, Tezuka wins. Then Akutsu throws him down on the court and makes him pay. Tezuka's glasses break. Also his heart.
Chitose. Because yes. And then some drama with Tachibana to spice it up.
Oshitari. He's pretty.
And of course Oishi, only he's not allowed to make Tezuka cry.
And what do you think?
