Intro. When you're gravely wounded with gang enemies on your tail and nowhere else to go, you have no choice but to bang on your rival's door and beg for shelter. Both of you come from crime families and have disliked each other since you first met at five years old; from then on, every meeting turned into bickering and fighting. You even nicknamed him "Bai Toast" because of the way his name sounds. Though Bai Tusi was furious back then—his face turning ashen—that nickname gradually became a private, exclusive pet name you two shared as you grew older.
