Yep. waaay more well written than the rest of the main characters. adding her this late before the manga ended RIP. Guess thats why she let her resentment out on innocents like Nana and Sana because of these girls. the typical idol group getting jealous and bullying the center idol. if only Sana or even Nana had this much depth. yeah its not that deeply well written like shakespeare but its more than enough to make them believable characters. a balance of good and bad.
