Because of a street scuffle, Dung is taken to a hospital for treatment by Khoa, a doctor who is passing by. Because of this, Dung makes a startling realization.

After learning about the details of Dung's situation, Khoa not only refuses to charge him for medical expenses, he even invites him home to stay the night.

As Dung and Khoa become closer, two unexpected people appear and try to tear them apart.

After hearing out Dung, Khoa begins to seriously wonder whether the two of them actually knew each other when they were younger, and he decides to ask Dung directly.

Khoa's assistant, Huynh, moves into Khoa's house because of a foot injury, and as a result of living under the same roof, Huynh and Dung start to get jealous.

One day, Khoa's sister pays him a surprise visit, but she doesn't seem to be happy with Dung.

Dung hasn't come home for a few days now. Coming to terms with his absence, does Khoa have a way to bring him back?
