S4·E29 Episode 29

CHUNG’s condition deteriorates. He cannot believe what he does subconsciously. He tells CHI that something is strange in his house and asks her to investigate. When she arrives, she sees CHING being tied up. He suddenly attacks her. She manages to call SANG for her. He takes CHING up to the roof. SANG and CHING both fall down from there. Luckily, they are only slightly injured. CHI has an internal bleeding. However, there is no matching blood in the hospital. HUNG knows that SHAN has the same blood type as CHI, so SANG rushes to find her. However, she is away from Hong Kong for business. KEN leaves a message on SHAN’s company website. When she learns about it, she rushes back to save CHI. CHUNG is hospitalized for mental treatment.
