Secret Door

Chi-kiu finds out Sum-yuet recognizes Siu-tin was the guy who snatched his car.

Siu-tin absconds just in time. Chi-kiu is taken to the police station for questioning.

Yan-hiu takes a statement from Sing-him.

Sum-yuet wants to sentimentalize the issues as she hopes to save her marriage to Ho-yin.

Sum-yuet is so upset that she hallucinates.

At Ho-yin's funeral, Yan-hiu turns up with new evidence, resulting in Mei-lam blaming Sum-yuet for causing the tragedy.

Sum-yuet realizes she has fallen into Mei-lam's trap.

Chi-kiu tells Sum-yuet about his past sufferings. The duo sympathize with each other as they tell each other their issues.

Yan-hiu tells Chi-kiu what she saw on the day of the robbery.

Siu-tin's appearance causes the chums to worry about nothing.

Yan-hiu sobers up. She interrogates Chi-kiu about last night when she was seemingly getting kissed against her will.

Yan-hiu reluctantly approaches Chi-kiu to thank him as she is asked by Chi-keung to do so.

Mei-lam is shocked to learn that Sum-yuet wants to take Chi-ching on a study tour.

Yan-hiu sends Chi-kiu some evidence that shows Chun-nam maliciously pushed his mother down.

Yan-hiu keeps looking for the brooch.

Sing-him's incident causes him to contradict his younger sister even more.

Chi-kiu is shocked as Sum-yuet comes clean about everything.

Sum-yuet realizes Chi-kiu and Sum-yuet are getting closer and closer to each other, so she slyly causes Chi-kiu to run into Emma as she hopes to make Chi-kiu stay away from Yan-hiu.

Yat-fung somehow recalls some black-clad guy entered and left Siu-tin's home, so Hei-yee pretends to be drunk and approaches that particular person to gather evidence.

Mei-lam is revived, but she suffers a stroke and is paralyzed.

Chi-kiu rushes to the scene and fearlessly saves Hei-yee.

Chi-kiu tells Hei-yee the investigation findings. The duo go to the hospital to ask Mei-lam about the falling down the stairs incident.

Chi-kiu holds the "incriminating evidence" in his hand and hopes Sum-yuet reveals the truth.

Sum-yuet goes with Siu-tin to catch Chi-kiu. While they scuffle, Chi-kiu is shot.
