Sing Hei has since moved back home but there's no improvement in his relationship with Kit Yee. He also attempted to look for a job but is reluctant to reveal that he spent 10 years in jail.
Sing Hei saw Pui Ka on the streets. He remembered her from his prison days. She was a social worker who approached him many times for counseling and interviews when he was in prison. Everytime Pui Ka visits Sing Hei in prison, she's the only one talking. Sing Hei doesn't talk or respond. Eventually one day he asked her why does she visit him. Her reply was she likes to help the inmates. Chatting with the inmates is a form of counseling and can help them to reduce stress.
It appears that Pui Ka is now an established news reporter. When Sing Hei was in prison, he told Pui Ka of his innocence and she believed him. She did not treat him with prejudice and he's grateful to her for that. Each meeting with Pui Ka brought hope for Sing Hei.
Sing Hei met Pui Ka for real outside her office. Pui Ka apologise to Sing Hei as she left for her studies in US without telling him. She also reassure Sing Hei that she treats him as a friend! Sing Hei says she is his only friend.
Filled with hope after his chat with Pui Ka, Sing Hei was ready to let go of the past, when he suddenly saw Keen Yip's company logo on his furniture. He asked Kit Yee if the furniture in the house come from Keen Yip's company and Kit Yee said yes. Even the furniture in Tse Leung house is also from Keen Yip's company.
Sing Hei is confused by Lap Yin's analysis. If the company logo are on all furniture, it doesn't proof that Keen Yip went to Tse Leung's house and dropped his keychain. Sing Hei realised that Lap Yin may have something to hide.
To probe further, Sing Hei went looking for Keen Yip at his congressman office. There he saw a China woman who asked Keen Yip for help but was turned away by Keen Yip. Sing Hei spoke to her and realised that she was with Keen Yip the night Tse Leung was murdered. Therefore, there's no way for Keen Yip to have killed Tse Leung! After talking with her, Sing Hei realised that Lap Yin had actually approached and questioned this woman before.
Sing Hei sent a "thank you" card to Pui Ka and asked her out. Pui Ka brought Sing Hei to church. She told him that it's good to have faith. She also introduced her boyfriend to Sing Hei - it turned out to be Lap Yin!
