Deerui's, I don't mean to be a hassle but this stuff has been done too many times when I've been here with various members saying "I'm quitting tbt" and specifically because her request thread hasn't been getting much attention, it's more or less a desperate move to get people to draw art for her, and when people have done their part, she'll come back saying "Thanks for the support and care, I can't leave now" and then the whole process will reset again sometime soon.
I have a 13 year old sister who's similar in ways, not art related but definitely still comes down as desperate to get something with attention.
Also a kind remark, Yui isn't actually Deerui's OC, it was stolen from another artist not around here, Deerui hasn't credited said artist whatsoever.
