Aw, you're not a burden, Shay, and it doesn't seem like you're trying to stay in her shadow. I'm sorry you feel that way. Dx If you really want to quit K-Con and cosplaying and stuff, then go ahead, but if you want to stop because of Sahara. . Doesn't that seem a bit ridiculous?
I don't have any siblings, so I don't know, but I don't think you should stop just because you think it seems like you just want to be with your older sister.
If that made any sense. xD
