Shibuya is a bustling place.
Liyuan lived here since she was a child until something happened when she was nine years old... She had to move away from this place and was forced to separate from Sangu
After moving to Setagaya, she became a little lonely, but fortunately she made friends with the Nakano brothers and sisters, Kitagawa Hamo Motoko, and Igarashi Mine.
At the age of twelve, in order to support Motoko, she established her own bosozoku "Canghai"
Then she led "Canghai" to become the number one in Setagaya step by step until she disbanded "Canghai" at the age of eighteen.
The battle with "Suzaku" hit her mentally and she suffered from mental illness. Before the New Year, Liyuan returned to Shibuya to visit the graves of her parents who died in a car accident, and met Takashi Mitani, whom she had not seen for a long time.
From then on, Mitani would often accompany her, and she also unknowingly developed a secret love for Mitani.
"Canghai" disbanded, and she devoted herself to jewelry design. She served as the chief designer of Delaime's jewelry brand, and accidentally collaborated with Mitani, who became a fashion designer.
Not long after, Mitsumi began to pursue her. From being unmoved at first to gradually wavering later, Mitsumi had enough patience to wait for her.
In the end, she accepted Mitani's proposal...
