In the winter of 1937, on the eve of the fall of Nanjing. The warlord marshal Gu Chenjian forcibly took away his adopted sister He Sisi and fled south. She hates that he specializes in cold blood, but she doesn't know that he left wounds under his military uniform to protect her; he hates that she is naive and reckless, but he secretly replaces the poisoned food in her bowl every night.
From Nanjing to Guilin, she pawned the buttons of her cheongsam to exchange for dressings, while he tore off the buttons of his military uniform and held them against bullets. When He Sisi finally discovered that her "execution order" in the study was actually a substitution plan, his own birth date was engraved on the unmarked tablet in the Buddhist hall.
"Gu Chenjian, why do you make choices for me?"
"Just because of your bite," he wiped away the blood from his lips, "it still hurts."
