Mystery Files - Season 1 Episode 19

KWAI was mentally ill. He waited for YIN outside the TV station almost everyday. KWAI knew that YIN and LEI were going to get married and was extremely jealous. A time traveller appeared and wanted to take WING away. WING saw in the future that YIN would be stabbed, but YIN refused to believe. WING rushed to the hotel and saw that KWAI was going to kill YIN. WING stopped him in time but he was stabbed. WING was hospitalised and YIN regretted it very much. He at last admitted that WING was his father. Afterwards, WING started to age rapidly and left with the time traveller. When LEI and YIN arrived in the hospital, WING had already left. He left a not saying about time travelling. YIN had no choice but only believe in this explanation. The day before their wedding day, YIN went to a karaoke bar with her friends. KWAU showed up and shocked everyone.
