Xu Zhiyu was admitted to the hospital after overeating, and unexpectedly discovered that the attending doctor, Su Qingyan, was actually her door-to-door neighbor.
She is a writer of social horror articles. The trauma of her original family makes her afraid of emotions.
Everyone only regarded Su Qingyan as warm-hearted and friendly, and no one knew that this encounter was the reunion he had been waiting for for seven years.
He slowly approached her through his identity as a doctor and neighbor.
Many misunderstandings lie between the two, and they both fall into a trough, facing each other across the wall, becoming strangers.
Until the fog cleared, Su Qingyan confessed her feelings:
"Meeting again is not a coincidence. Waiting is always done willingly."
