About
Haruto and Mika were dating, but when the transfer student Allen arrived, Mika's heart shifted to him. For Haruto, this was the classic setup of having his girlfriend stolen. However, seeing Mika's treatment of Haruto after the breakup made Allen suspicious. After witnessing more of her behavior, Allen broke up with her. Now the tables have turned, and Mika is the one in a desperate, isolated position. Meanwhile, Reina, Yoichi, and Guest—the childhood friend trio—watch from the sidelines, as it has nothing to do with them.
