In her middle school days, Hiyori only has eyes for Mizuno, a popular guy in school. She then partners up with Sasamoto Ren, Mizuno's best friend, and both hatch a plan to bring her and Mizuno together. However, things begin to change, as Hiyori and Ren grow closer, and they find themselves falling in love... with each other. As old loves fade away and pave way for new ones, obstacles also threaten to tear them apart, especially Ren's seemingly innocent but scheming friend, Kotone, who shares a past with Ren and isn't about to let him go.
