Someone said goodbye and turned around forever;
Some people say goodbye, but they are destined to be obsessed with each other for a lifetime;
Seven years ago, Tong Yiyi met young Zhuo Lulin in an alley on a rainy night.
He pulled her and ran wildly, with a sinister look on his face, but he was hiding a secret.
She kept saying "wait for me" for seven full years.
He is a police academy student who goes deep into the darkness to work as an undercover agent. He cannot help but disappear without a trace.
She held on to her memories, survived her youth, and grew from a girl to an adult.
Seven years later, he returned from a bloody battle, taking off his disguise and looking completely weathered.
When they met again in the ward, he looked at her with red eyes:
"I'm back and I'll never leave again."
Intent: Waiting and redemption in darkness
