[[ FADING ]] . . . S A Y S - - !!
Oh wowwie my list would stretch the page xD
But here are my top three:
o1- They both changed each other's worlds :] Everyone has a soul mate, but Ichigo and Rukia had such an amazing impact on each other's lives. Once they met each other, their lives could never go back to normal. And i believe both of them like their new lives much better than how it was before. Maybe part of it is because of the other ;D
o2- How they just keep coming back to each other. This is really corny, but their fates are quite obviously interwined. Even though they took different paths multiple times, they just keep ending up back together again
o3- All IchiRuki fans gotta love the love squables. One cliche phrase to sum it all up? "They argue like a married couple" xD
