Hatefriends really is hilarious - Haruka's real face is a little different from Charlotte's, I'd say? Haruka's more intelligent and detached than anything, but she also really, really likes being in control of every situation she's a part of. She usually goes for the flirty, confident approach, but in reality she's a lot more cynical and self-interested than she lets on.

Anyway, I'm glad you like the ideas so much! I'll tag you on the TDM.
