At 18 years old, Emiko felt like things could not get any worse after her highly publicized and embarrassing breakup with her ex-boyfriend. However, hope came in the form of a good-looking guy who offered her tickets to an upcoming rock concert in the middle of the street. This generous stranger turned out to be one of three brothers from the Kanita family: Gaku at 18, Youji at 19, and Masaki at 23. Emiko's chance meeting with Youji led to a whirlwind romance. Despite his impulsive, hot-headed, and somewhat self-centered nature, Emiko found Youji's honesty to be refreshing and ended up falling for him deeply.
However, their relationship faced an unexpected hurdle when Emiko discovered that Youji and her old middle school friend Yuri knew each other long before Emiko met Youji. The tension between them was palpable, and Emiko was left wondering what had happened between Youji and Yuri.
