“This is the story of Haruka, a girl who left the countryside to start her college life at Tokyo. She’s secretly in love with her co-worker, Kurotaki, but she doesn’t have enough confidence in herself to confess her feelings to him. That’s until she meets Hikaru, a fashionist girl that’s willing to help her. However, Hikaru’s not what she seems to be.”
