A third-tier star, Lu Weiyu, an ordinary beta, urgently needs a backer.
After finally getting into the marshal’s banquet, just about to strike up a conversation——
Marshal raised his phoenix eyes and said, “Get lost.”
Lu Weiyu rolled away non-stop, and was pulled back by the marshal before he rolled away.
With a low voice and domineering eyes, the Marshal put him in his arms: “Did I tell you to get out? Get back.”
Lu Weiyu nodded tremblingly.
The marshal surrounded her, humming: “If you touch someone, you will be responsible to him.”
Lu Weiyu was dumbfounded, and said nonsense: “Okay, take responsibility.”
The marshal pinched the man’s chin and snorted coldly: “What are you responsible for? Women, don’t play with fire.”
…
It was only later that Lu Weiyu found out that the marshal had fallen ill again.
Marshal: “I hit you with my life.”
