i dont think he knows. if he did, i bet hed be a little depressed and question Rukia. thatd probably make them closer.
hmmm. aaaaaaaaaaaaand, Rukia did have romantic feelings for Kaien. she just backed off, knowing he had a wife and it was prbly just a little crush. anyway, if there were any official coupling for Ichigo. itd probably be the end of the series. if he ended up with Orihime, and it isnt gonna be the end of the series, theyd just break up. even tho im in support of IchiRuki, him and Ori make more sense, both being human n all. leave it to Kubo to surprise us! thats one of the reasons i watched Bleach anyway. its diff. not too much couple stuff
