A spin-off work set on an adulterous journey of a married woman, directed by Hirokazu Takahashi. The protagonist, Tae, is 38 years old, with no marriage history or children. She has always sought the courage to change something in her life. Born into a family where her father, an adopted son-in-law, had a bad relationship with her grandparents, the bond between her parents was also distorted. After graduating from university, she experienced her first love and lost her virginity at age 24. Though she went through several relationships afterward, none led to marriage. Before she realized it, she was approaching the milestone of turning 40. Forced to make decisions about her future, she embarks on a journey to reflect on her past. On this journey, the truth hidden deep within her troubled heart gradually comes to light.
