Liam was a single father who had been raising his 2 children Tommy, 7 and Tracy, 6 since the death of his wife Paula. He wrote books and sold them to earn a living. Despite having a knack for script writing, Liam was not as adept in marketing. As a result, his books were not selling well, and so finding enough money to feed the family was a problem.
One day, Liam suddenly had nosebleeds. At first, he ignored them, thinking that he was too stressed at work. However, when his nosebleeds became frequent, he realized something was wrong. There, he received shocking news. He was diagnosed with leukemia, and the only way out would be a bone marrow transplant. Although friends and acquaintances had tested their bone marrow samples for compatibility, none were compatible with Liam's, much to his disappointment. Still, he refused to give in to despair. Besides wanting to watch Tommy and Tracy grow up, Liam also wanted to look for his long-lost younger brother Nick, whom he had been separated from since childhood after their widowed father passed away due to an illness. He remembered wandering around the streets with Nick after their father passed away, and they crossed paths with a group of human smugglers who tried to smuggle them to a foreign country to become child beggars. They were separated while trying to escape from the human smugglers. Fortunately for Liam, the police had been tipped off and the human smugglers were apprehended. After this incident, he ended up in an orphanage. However, he had no idea where Nick was, and whether he was still alive.
Just then, doctors told Liam that they had found a bone marrow match for him. The donor is Lawrence Lam Tung-ho, an inmate who is currently serving a 8-month prison sentence for obstruction of justice. He tested his bone marrow sample after hearing about Liam's plight through a cellmate, who was also a friend of Liam's friend, and after finding out his bone marrow sample is compatible with Liam's, Lawrence promptly expressed his intent to donate. The operation would be scheduled for the next day. Upon hearing the good news, Liam shed tears of joy. He started making a list of to-do things after his discharge.
The next day, Liam met Lawrence outside the operating theater. Both men felt a sense of closeness with each other. They exchanged a brief conversation before being wheeled into the operating theater simultaneously. The operation was a success. As Liam laid on the hospital bed after the operation, he caught sight of Lawrence, who was being escorted back to prison. "Thank you," he whispered. Lawrence caught his gaze, and the 2 men smiled at each other.
Liam recovered swiftly. After he got a clean bill of health, he promptly visited Lawrence in prison as promised. From there, he learnt about the latter's plight. Lawrence found himself in an orphanage when he was 6 years old. He did not remember his own name and how he ended up there, so the orphanage director named him Lawrence. After he left the orphanage at 18, he worked several jobs. Over the years, he managed to achieve professional success through hard work. He also had a relationship with a girl named Alexa, who worked as an exotic dancer at a sleazy bar. However, she was very dishonest as she constantly stole from guests. As the saying goes "Love is blind", so despite Alexa's dishonesty, Lawrence was head over heels in love with her, and believed he could change her. One day, as he was working, Lawrence got a call from Alexa, asking him to help her. She was caught red-handed stealing from a guest yet again, and she escaped while the guest was calling the police. Lawrence met Alexa secretly, and before he could ask her anything, he saw a few police officers walk towards them. Knowing that they were looking for Alexa, Lawrence helped her evade police pursuit. He found this scene familiar, but he could not put a finger to it. However, he suffered from a headache while evading the police. In order to escape, Alexa abandoned him, causing him to be arrested by the police. Lawrence tried to take the blame for Alexa when arrested, but the guest, whose valuable was stolen by Alexa, testified for him. Lawrence was nevertheless charged for obstruction of justice, and was sentenced to serve 8 months in prison. Alexa was later caught, but she blamed Lawrence for her arrest, and scolded him for being 'useless'. After hearing Lawrence's story, Liam felt something click inside him, as he had also lost Nick when the latter was 6 years old. At the same time, he felt sorry for Lawrence about how he ended up in prison. Since Lawrence did not have a home, Liam promised to take him in after his release.
Since then, Liam would visit Lawrence regularly, and they would update each other about their respective progress. Lawrence was granted an early release due to good behaviour. Liam picked him up from prison and took him in as promised. Tommy and Tracy got along well with Lawrence, and he would share with them his life experiences. Liam also gave him a job with his book publishing company. As Lawrence was adept at marketing, Liam's books started selling like hotcakes. Things started to look up for them, and especially for Lawrence, who had not only turned his life around professionally, but also personally, as he began a relationship with a co-worker Natalie, who used to be a drug addict, but had turned over a new leaf after a stint at the drug rehabilitation centre. As for Liam, he moved on from Paula's death and started a relationship with Annie, a nurse who took care of him during his hospitalisation.
One day, the employees of the book publishing company were heading out for a company lunch after a meeting. In his hurry, Liam accidentally left his wallet on his work desk. When Lawrence saw it, he picked it up and wanted to return it, but in his haste, he accidentally tripped over a furniture and fell. Liam's wallet also fell from his hand. A photograph fell from the wallet, which revealed Liam's childhood photo. Lawrence saw himself in the photo too. Suddenly, he felt his head spin. Fragmentory memories of his childhood appeared like pieces of jigsaw puzzle. Just then, Liam appeared at the door. "What's wrong, Lawrence?" he asked. Lawrence revealed that he remembered everything. His real name was Nick Chong Wing-hong. His mother passed away when giving birth to him, and his father raised him and his elder brother single-handedly. When his father passed away due to an illness, they wandered around the streets. Suddenly, they crossed paths with a group of human smugglers, who tried to smuggle them to a foreign country to become child beggars. They were separated while trying to escape from the human smugglers, and in the process, Nick tripped over a tree branch and ended up falling and hitting his head. When he woke up, he found himself in an orphanage, and he was renamed as Lawrence Lam Tung-ho. Nick then mentioned how he helped Alexa evade police pursuit, the reason for his imprisonment, saying that he now understood why it seemed familiar to him.
Upon hearing his revelation, Liam could not believe his ears, as Nick's story during childhood tallied with his. "It's me, Nick. I'm your brother," Liam said. He then told Nick what had happened to him throughout the years. "I'm sorry for not recognising you sooner." He and Nick shared an embrace. They decided to do a DNA test to confirm their findings, and when it came out, it shows they are biologically related. Liam and Nick were glad to have found each other after years of being separated. A year later, a double wedding was held, with Liam and Nick getting married to Annie and Natalie respectively. The story ends with both couples celebrating their double wedding with friends and families.
