Fuichi oh Fuichi. At first I thought Qian-Fan and Fuichi would be the best of friends, after all there was that promise of tea sometime after they met in the sick bay, but the differences began to appear and they would be too much to overcome.
First off, Qian-Fan really does avoid close friendships. His past history with his insane mother meant he desperately avoids forming bonds until he's known the other for a long time.
Secondly, Qian-Fan is not a pacifist and was having troubles with Fuichi's views on Dageki, but he kept them to himself.
Then came Hurricane Junpei and another fundamental disagreement. Yes Qian-Fan was harsh on Junpei, but he felt it entirely necessary. Innocent investigations have led to fallen Phoenix in the past and it needed to be ended now. If Qian-Fan's initial advice to the Captain had been taken then Junpei would have been executed before he could be handed over to the Lankans. Had this been done then they would have missed out on the information the lessons would have given. Hence Qian-Fan's presence at the lesson. Not as Fuichi thought to oversee Junpei's punishment, but rather to share it as atonement for almost losing the Rokugani this chance to learn how to defeat a possible enemy.
And of course, the major disagreement between them - O-Washi. Any chance of the two being friends disappeared with the drunken 'Can I join you?' line. A total indiscretion going against everything Qian-Fan believed in. Just hearing it said was enough to scandalise, never mind it being directed at the man Qian-Fan was growing to like very much. Any offer to 'share' as you hinted in your thread would have caused a small explosion and a lecture on proper manners and discretion. Yeah . . . to a Crane.

In all Qian-Fan thought Fuichi to be an all too pretty, naive, flirt of a man whore.
