When they first met, Qin Luo said to Liu Qingxuan, "Why didn't you open the door at home? Didn't you know there'd been a murder across the hall?"
When they met a second time, Liu Qingxuan said to Qin Luo, "How about I stay at your place? Someone died across the hall, and it's pretty scary."
By the third meeting, they were wishing each other good morning and good night every day.
Liu Qingxuan:
As the years passed, her appearance never changed.
By a twist of fate, when she returned to a familiar place,
She saw a face like someone from her past beyond the door,
And couldn't help opening it, getting caught up in someone else's karmic debts.
Qin Luo:
After graduating from the police academy, she solved one strange case after another.
She followed procedure, responding to calls as they came in,
Until one murder case brought her into contact with the person who reported it.
In the end, she couldn't stop herself from losing her heart and stepping into someone else's karma.
The truth, too, slowly comes to light through one mysterious case after another.
