I mentioned on my personal blog months ago about Blake being a fairly young author gaining popularity. Ruby is a big fan of Blake’s work and bumps into her in a coffee shop in a secluded part of town. She basically tells her how much she loves her books in her awkward Ruby way and every chance she gets she goes and talks to Blake about heroes, villains, and other magical things and about her next book.
Also Blake writes smutty romance novels under a weird pen name (no clue what it is you can make one up) Yang finds out but Blake tells her not to tell Ruby. Thinking she’d lose all respect of Blake. Obviously Ruby wouldn’t mind but Blake is paranoid about it.
