Pak Kiu has passed his interview for promotion and now has to return to P.T.S for training before he can officially be an IP (Probationary Inspector of Police). Yuk Bo and Pak Kiu go for their morning run. Yuk Bo notices that Pak Kiu is sad because of Lap Man and buys him breakfast to cheer him up.
Some triad members caused trouble at Lap Man and La Ba's street, where they collect parking fees. It appears the street is under Jor Lun's (a senior level member if Chun Hing) watch. The triad members beat Lap Man and La Ba up, until Lap Man says that he is a follower of Laughin.
Jor Lun then goes to Mega Disco to look for Laughin to settle the matter. Jor Lun challenges Laughin and they could not settle the matter between them. They looked for Hau Ko and Hau Ko award each of them half of what used to be under Tin Chat. Both Laughin and Jor Lun is happy with that solution.
On Pak Kiu's last day with the E.U team, they spot a group of people spraying paint on a glass window. Pak Kiu and the team gave chase. It appears the one Pak Kiu is chasing is Lap Man. They other two violators were caught, but Lap Man managed to escape by jumping off a bridge onto the back of a lorry.
Yuk Bo goes online and bid for a purse for Fa Si Lai. They seller turns out to be Yau Yau. They also shared a taxi to go over to Pak Kiu's place for a party. At the party, Pak Kiu realises that Yau Yau is Kong Sai Hau's daughter and everyone quickly distance themselves from her. They said many unpleasant words and ask Yau Yau to leave immediately. Pong also tells Yau Yau not to show up for work anymore.
Hau Ko finds out that Yau Yau is sad because she lost all her friends. He looks for Lap Man and asks him to befriend Yau Yau again. Lap Man turned down Hau Ko's request but secretly leave messages for Yau Yau on her blog. He advises her to turn her lies into reality. Yau Yau decides to go travelling round the world and visit the places she wrote about in her blog. Sam Jie decides to accompany Yau Yau on her travels.
Approximately, 1 year later
Pak Kiu graduates from P.T.S and is now an Inspector. He has joined O Kei, or Organised Crime and Triads Bureau, under Wu Sir. Pak Kiu's team is focus on crimes which involves the illegal lending of money and loanshark matters.
During a meeting, Pak Kiu receives a report that someone wants to commit suicide because he is harassed by loansharks who sprayed his house with red paint. Yuk Bo's E.U. team was the first to arrive on scene, and later joined by Pak Kiu's team. She advised the victim based on her own experiences and successfully managed to save him. Pak Kiu was impressed with her improvements within this one year.
The victim, Peng, decides to work with the police to nab the loansharks. Pak Kiu gives Peng marked money to be handed over to the loansharks. The loanshark is actually Lap Man. Pak Kiu trailed Lap Man back to an office which is one of their offices and catches him. However, they could not find any evidence to charge Lap Man.
Hau Ko praises Lap Man and Laughin for their quick thinking and smart move. When Lap Man and Laughin realise they were followed, they quickly find ways to throw off the police. Lap Man also "bring" the police to the wrong office, while Laughin gets help to remove evidence from the other office. The police get Peng to identify Lap Man from a line up but he claims he could not recognise anyone. Actually Laughin kidnaps Peng's son so he has to collaborate with Laughin.
Sam Jie and Yau Yau return from their travels. Yau Yau tells Hau Ko that she is now writing a book after a publisher discovers her blog and is interested in her travel stories. She left a note on her blog saying that she will return to her old house to take some photos for her new book as well as to visit La Ba. When Lap Man reads that she will be visiting the next day, he quickly deletes his browser history and cache so that Yau Yau will not find out that he is "Lucky Prince".
Hau Ko accompanies Sam Jie to dinner. The dinner is prepared by the same Chef who taught Sam Jie cooking when she was in France. The Chef even made heart-shaped dessert for Sam Jie and praised her lavishly. When Hau Ko heard their conversation, he was a little jealous.
Laughin encourages Hau Ko to pursue Sam Jie but Hau Ko is reluctant. Laughin suggest to base on the toss of a coin and decides who gets to pursue Sam Jie. Laughin wins. Laughin goes jogging in the morning with Sam Jie and Fai Ye. He tries to test Fai Ye's reaction should Sam Jie re-marry. Fai Ye says it's alright for Sam Jie to remarry but hopes that it won't be Laughin. Laughin sends Sam Jie her favourite flower and confesses his love to her.
Laughin continues to profess his love for Sam Jie and claims that he has been in love with her for 9 whole years. He also reveals to her that many of Tin Ko's romantic gestures were in fact his idea and he was the one who taught Tin Ko how to court Sam Jie. Laughin then tells Sam Jie about the shop which she was suppose to operate with Fa Si Lai; Laughin tells her that he rented the shop for over a year just in case Sam Jie wants the shop again.
Sam Jie was very touched by Laughin's gestures and thoughts. She was in a predicament and shares it with Hau Ko. She tells Hau Ko that there's no doubt that she's touched by Laughin but sadly, she does not feel the same way. She reveals to Hau Ko that she doesn't know how to reject Laughin and Hau Ko promises to help her take care about it and tells her not to worry.
Hau Ko talks to Laughin and tells him to leave Sam Jie alone as she only wants to be friends with Laughin. Laughin says he is not fighting for Sam Jie with Hau Ko, he is merely showing Hau Ko what can be done to woo Sam Jie.
Even though Sam Jie tells Hau Ko to release the shop, Hau Ko goes behind Sam Jie's back and convince Fa Si Lai to start their business. Hau Ko and Fa Si Lai discuss about the operations and renovations but their actions were soon discovered by Sam Jie. Fa Si Lai apologised to Sam Jie and she agrees to start their restaurant business.
There is a new group of thugs called "Head Hitters" where the thug uses a helmet to hit the head of the victim before robbing them. The E.U. team has been notified and was told to be on the look out for any suspicious persons. La Ba was holding a helmet and was stopped by E.U. Lap Man was nearby and came to La Ba's aid. La Ba noticed that there's a few more days to Lap Man's birthday. He buys a cake and brings over to Yau Yau's place. He asks Yau Yau to bring the cake over and celebrate Lap Man's birthday with him. Yau Yau declines initially but goes over on her own. She cooks a meal for Lap Man but he never shows up.
Lap Man spots a "head hitter" and chases the suspect. Police managed to catch the suspect and Lap Man has to give a statement to the police. Pak Kiu stops Lap Man as he was leaving to wish him Happy Birthday but Lap Man was cold towards him. Pak Kiu offers to celebrate with Lap Man but Lap Man refused. He goes home to find the meal cooked by Yau Yau on the table.
Wu Sir calls Lap Man out and gave him a fishing rod for his birthday. Lap Man celebrates his birthday with Wu Sir near a night fishing spot. Coincidentally, Pak Kiu was there too with Yuk Bo. As Pak Kiu was leaving, he saw Wu Sir's car as well as Lap Man on his motorbike. Pak Kiu was suspicious of their relationship and confronts Lap Man.
