About
Haruto and Mika were dating, but when a transfer student named Allen arrived, Mika's heart shifted toward him. For Haruto, this was the classic setup of having his girlfriend stolen. However, seeing Mika's treatment of Haruto after the breakup caused Allen to grow suspicious. After witnessing more of Mika's behavior, Allen broke up with her. Now the roles are reversed, and Mika finds herself in the desperate position she once put Haruto in. Meanwhile, Reina, Yoichi, and Guest—the childhood friend trio—watch from the sidelines, completely uninvolved in the drama.
