I hate Temari with a passion. I'm also not a huge TenTen fan. I think my loathing for Temari comes from me being a ShikaIno person, but she's also annoying in general.
A very tough question. I love both of them for different reasons, but I have to say it's a dead tie. I hate to be a fence straddler, but this is a sensitive topic hahahaha
Renji/Rukia By the far the best. Byakuya/Rukia Ichigo/Senna Ichigo/Orihime Uryu/Orihime Grimmjow/Orihime Ulquiorra/Orihime Shunsui/Lisa Shinji/Hiyori Gin/Rangiku Toshiro/Momo Toshiro/Karin
