After Qiao Yi died in a car accident, she came back to life thirteen years earlier. She finally found the boyfriend she had in her previous life, but in the blink of an eye, he married someone else. Just when she couldn't understand why Heaven had given her another chance at life, he suddenly barged into her world. Little by little, she came to understand what fate had arranged.
The first time they met, he said, "Getting home late? Afraid your mom will beat you?"
The second time, he said, "Why aren't you saying anything? Scared stiff?"
The third time was at university. He was Qiao Yi's military training instructor. He said, "You're still a kid."
The fourth time, he was injured on a mission and hospitalized. She went to visit him and said, "I've already seen the smaller version of you. I'm even more curious about the latest model after its upgrade." He leaned close to Qiao Yi's ear and quietly asked, "Are you sure you want to see?" Qiao Yi promptly fled.
Later, she waited for him for three years, all because of one thing he'd said: "Wait for me to come back."
"What are you doing?" "Getting ready to cook." "Cook? Did you get transferred to the mess hall?"
"Uh... I'm on leave. I'm cooking at home."
He said, "My world is small, as small as the military camp that confines me. My world is also vast, as vast as the country I protect. A lifetime in uniform, never wasting my youth; a lifetime by your side."
Only later did she finally understand: it was all so she could meet him again, and meet a better version of him...
