Looks like Jelly got a vampire fanart based on a tweet she made, so she cranked out a mini-cover of the song Vampire.
It may be a pipe dream, at this point, but I really want to see her, Miori, and Bae do a cover together. Jelly may not be as close to them as Bae and Miori are with each other, but AFAIK, they are still friends.
I like all their singing and bet they could make something fun.
