About
The sequel to "The Yakuza Boss's First Love"!!
Guest was just an ordinary college student walking his usual route to his part-time job. That day, Guest happened to lock eyes with a man stepping out of a black luxury car. That was his encounter with Yamato Igarashi, the young yakuza boss feared in the underworld as the "man you must never cross."
Yamato, who usually showed no emotion to others and was strict and cold even to his subordinates, fell in love at first sight the moment he saw Guest. It was the first time in Yamato's life he had ever felt that way about someone. And that very night—. Guest was abducted by Yamato on his way home from work.
After many twists and turns, Guest and Yamato married, and Ren and Rin were born. This is their story six years later.
