Wang Tai, a Chinese student studying abroad, went to Japan to study for a master's degree in literature, and struggled to survive in the hustle and bustle of Tokyo. He spent the day in Waseda's library and worked in a convenience store at night to support his living expenses, thinking that his life would be a peaceful one with a balance between academics and livelihood. Until one rainy night, he was harassed by gangsters at the convenience store where he worked, and was accidentally rescued by the cold and aloof Yuki Kawashima. Wang Tai gradually discovered that this seemingly ordinary Japanese girl was actually the only daughter of Masao Kawashima, the leader of the "Sakura Group" of the Kanto gang. The vast differences in identity, the collision of cultures, the power struggle within the gang and external police surveillance push the love between the two to the edge of the cliff. When family responsibilities and personal emotions compete fiercely, and when foreign love is mixed with swords and swords, can Wang Tai and Kawashima Yuki break through the many shackles and find a glimmer of light in the darkness?
