Pui Ka and Sing Hei visit Dai Gao at the hospital. Pui Ka was curious how Sing Hei and Dai Gao managed to succeed trapping Lap Yin.
Sing Hei's explanation: The whole plan started when Sing Hei knows that Dai Gao is involved in the Jack Tung case. He knows that Dai Gao is an honest man and is hesitant to accuse Lap Yin of bribery. He also knows that Lap Yin cannot walk away from the Jack Tung case and would use Dai Gao as his scape goat. But what surprised him was Lap Yin was willing to give Dai Gao a huge sum of money to get away from Hong Kong. And that's when Sing Hei realised that Lap Yin may be up to something else.
When Sing Hei found out that Lap Yin had paid Dai Gao off, he then changed his plan and used Dai Gao too. Sing Hei explained to Dai Gao that Lap Yin killed Tse Leung 10 years ago, killed Roy off as well and now Dai Gao is in danger too as he knows too many of Lap Yin's secrets. Sing Hei also advised Dai Gao to inform the police of Lap Yin's misdeeds. Dai Gao has to surrender that he has accepted "payment" from Lap Yin. If he doesn't tell the police now, he will also be embroiled in the whole mess.
Sing Hei managed to persuade Dai Gao to work with the police. Sing Hei also suggested tot he police to set a trap for Lap Yin. The police in-charge of the case, Lee Sir was supportive of his idea. Dai Gao said he felt taht he has betrayed Lap Yin but Sing Hei assured him that if Lap Yin has no bad intention, he would not fall into their trap. If he did fall into the trap they set, then it is clear that Lap Yin had bad intentions.
Sing Hei said in his plans, the only surprising factor was that Kelly had sided with Lap Yin. He never imagined that Kelly would betray him. Kelly was just standing at Dai Gao's room door and heard what Sing Hei said.
Kelly ran off and Sing Hei chased after her. Sing Hei told her that he doesn't blame her for siding with Lap Yin as he was the one who "used" her first. Sing Hei apologised to Kelly but she slapped him! She said that she hated him for cheating her of her emotions and love. Kelly explained that most of the staff has left the company, she would leave too. She will visit her parents in Los Angeles and will not return to Hong Kong.
Hoi Man will place Leng Ma in a nursing home and she will start looking for a new job. Kit Yee offered to let Hoi Man stay at their place but she declined. Sing Hei asked if she needs monetary assistance but she said she is fine.
Finally the truth is out. Kit Yee and Cheung See knows that Sing hei did not kill Tse Leung. Kit Yee and Sing Hei's relationship has also improved. They plan to have a family dinner at home but Kit Yee forgot to buy chicken to cook Sing Hei's favourite dish. She asked Cheung See to start cooking while she goes to the market.
Lap Yin kidnapped Kit Yee when she was at the market. After 2 hours Kit Yee is still not back from the market. Sing Hei and Keen Yip decided to go and look for Kit Yee at the market. The poultry seller said Kit Yee has left a long time ago, but he saw her with a man about Sing Hei's age. Sing Hei received a phone call from Lap Yin. He wants HKD 500,000 to escape.
Sing Hei and Keen Yip decided to inform the police that Lap Yin has kidnapped Kit Yee. The police were on standby at the place Lap Yin wanted to collect ransom but the person who picked up the ransom is not Lap Yin. He paid someone to get the police off his tail. He then waited for Sing Hei near his house and attacked Sing Hei from the back.
Lap Yin brought Sing Hei and Kit Yee to the building rooftop that they like to go. Lap Yin scolded Sing Hei for being naive.He said he doesn't want money, he wants Sing Hei to die. Lap Yin said he helped Sing Hei to kill Tse Leung and Sing Hei should have thanked him for it. Lap Yin then start to hit Sing Hei while Sing Hei tried to fight back but his hands are bound behind him. Kit Yee tried to help but was hit by Lap Yin and fainted.
In the course of their fight, Sing Hei fell and hit the send button on his phone. The last call he made was to Pui Ka and she answered. She heard Lap Yin and Sing Hei arguing. She also heard the sound of aeroplanes and knows their location. She then informed Lee Sir.
Lap Yin used a brick to hit Sing Hei's arm. He told Sing Hei that between the 2 of them only one can live, they way down for the other person is to jump off the building. Lap Yin then dragged Sing Hei and attempt to throw him off. He then saw Pui Ka arriving and waited for her at the staircase and kidnapped her too. He tied her up and place her next to Kit Yee. Meanwhile, Sing Hei attempt to use Lap Yin's broken spectacle lens to cut rope that Lap Yin used to tie his hands.
Pui Ka offered to go away with Lap Yin if Lap Yin promised not to harm Sing Hei. Lap Yin was about to stab Sing Hei when Sing Hei punched him. He then tried again, but this time, Kit Yee ran and blocked Sing Hei so Kit Yee was stabbed. It's then a full blown fight between Sing Hei and Lap Yin while Pui Ka watched helplessly. In the midst of all the chaos, Lap Yin charged at Sing Hei but Sing Hei avoided, causing Lap Yin to throw himself off the building. Luckily Sing Hei managed to grabbed on to Lap Yin's hands. Lap Yin asked Sing Hei to let him go but Sing Hei refused. He would rather die so he decided to jumped off.
Fortunately, there were some boxes and airbeds to cushion Lap Yin's fall. He didn't die but paralyzed from waist down. Leng Ma still treats him as her son and visited him at the hospital.
Kit Yee also managed to survive. She apologised to Sing Hei for misjudging him all these years. Sing Hei hoped that they will start anew and let bygones be bygones.
The court has decided that all Fei Ba and Gramndma's will will be handed to Leng Ma and Hoi Man. Hoi Man will send Leng Ma to US for treatment. Alex has also get together with Hoi Man. Pui Ka will also go to Beijing to further her career. Sing Hei confessed his feelings to Pui Ka again and asked her to meet him at Avenue of Stars. He will know her decision if she didn't turn up but hope that she will. But in the end, Pui Ka didn't show up.
Three Years Later:
Sing Hei bumped into Kelly. She has returned to Hong Kong and will be getting married soon. Sing Hei is now working as a counselor. Kelly also informed Sing Hei that Pui Ka has returned from Beijing.
Sing Hei goes to prison to visit Lap Yin. There, he met Pui Ka at the waiting area. Both of them visit Lap Yin together. Lap Yin misunderstand and assumed that they are dating. He vowed to exert revenge after he was released.
