Kano is courted by numerous other men but according to some viewers of the movie he only really loves Soji. I'm not sure exactly where that idea comes from except from possible pointers towards the end of the movie. But if true, this would be highly ironic, given that a point is made of Soji being fiercely antipathetic to same sex love. Earlier in the movie it is specifically stated Kano and Tashiro are an item. So why does he accept the command to kill him? This in turn is because the powers-that-be suspect Tashiro of committing murders from jealousy. But as the movie concludes it seems rather more likely that Soji may have been responsible due to his hatred of same sex love, in which case, if Kano loved Soji, it may make sense that he killed Tashiro to cover up for Soji who was actually the one he loved. Was Soji running back claiming he'd forgotten something really to get away to murder someone else - even perhaps Kano? It all gets really impenetrable. I suppose you can reach your own conclusions depending on which pieces of the jigsaw you select. The above is only predicated on the emphasis some comments have put on Soji and Kano's supposed love for him. But I'm not sure I accept that anyway. Still, it's a beautifully produced, atmospheric movie with an androgynous and beautiful lead. Alas youth is fated to be cut down for even the most beautiful like the cherry tree at the end of the film. I think that's a common metaphor in Japanese culture.
