Having the one person in Soul Society who should have been the person you looked up to most turn on you is reason for "being a problem", Yumichika. She didn't react well before. I doubt she's going to react well here. Understandably so.
Do not get in the way, then. If our dreams mean anything, it seems at least in the dreams, I mean just as much to Rangiku as Gin Ichimaru does, if not more. She's willing to step in between us as she knows both of us well enough to understand that neither of us would hurt her, and she is perhaps the one thing that could intervene in a fight between us. I hope that it does not come to that again.
I agree that it is distasteful, but for now, as long as I know someone else is watching out there, I'll be content.
