"The absurd adventure of a Chinese international student in the world of Yakuza, Japan - beneath the surface of cynicism is the desire for freedom and belonging."
The protagonist Du Xiaojie has everything that ordinary people envy: a prominent family background, endless money, outstanding appearance, and excellent fighting talent. However, he has lacked the warmth and stable friendship of his family since he was a child, and has learned to protect himself with cynicism during the constant relocation. After studying in Japan, he accidentally entered the world of Yakuza - not for money, not for power, just because of "fun."
In this world full of danger and temptation, he will encounter all kinds of Japanese women, brothers who share life and death, and ruthless opponents. Every seemingly absurd adventure quietly changes his understanding of life, feelings, and responsibilities.
