Emerlad's highschool life started out a little boring for her. Indeed she mostly stay at home and play video games. She's different from girls at her school. Quiet, Mysterious, and a bit Arrogant. In order to stand out more, she pretend that she's Harriete. A girl who has the opposite personality as Emer's. And pretended that Harriete's her older sister. And Perseus, a boy from her class, falls in love with Emerlad's sister Harriete?? He doesn't really know that their the same person. Perseus was always Emerlad's type... What if he founds out the truth? What would Emerlad do?
