Struggling to suppress her mounting frustration and loneliness, she finds herself trapped by her own unfulfilled desires. The situation takes a dramatic turn when Misako discovers that the persistent caller is none other than Kazuhiko.

He soon sets his sights on Emiko, Misako’s younger sister, complicating an already fragile dynamic. As their involvement deepens, Misako is forced to navigate the dangerous tension between hiding the illicit relationship from Yosuke and facing the very real threat of losing Kazuhiko to her own sister.
