I don't know if Alex would have any interest in men but if he does he could be one of Kiyoshi's exes or hookups or something of the sort?

Koutarou, whom I already have in game, has in the past and not as much in the present, gone to the ER because he gets into various accidents because he draws and walks at the same time. At most it's a broken bone ot two, but most people working at the ER would have tired of this weird guy.. But maybe Alex could have treated Koutarou's injuries at some points?
