Ask for a movie ~ I hope everyone can help (preferably in detail)

Wei Qing, a Hong Kong girl, witnessed a traffic accident that killed two friends during a trip. Since then, she has become introverted, depressed, speechless and addicted to surfing the Internet all day. On the Internet, she met Ali, who runs a tourist resort hotel on Koh Samui. He also had a car accident, and his lower limbs were inconvenient after the injury. But he is open-minded, cheerful and hospitable, which makes every passenger there feel comfortable and full of joy. Wei Qing came to Koh Samui at the invitation of Ali. Ali's chic and lively personality and positive and optimistic attitude towards life deeply touched Wei Qing, and her heavy heart rippled. Encouraged and infected by Ali, she bravely faced life, got up the courage to drive and carried Ali in the open land. Severe bumps and vibrations almost caused Ali's old injury to recur. Wei Qing felt guilty, but Ali was really happy for Wei Qing's psychological recovery. Mutual help brought the hearts of the two young people closer together. Ali's injury obviously healed, but it happened to Wei Qing again. A strange disease that even doctors can't do anything about makes her haggard and senile. In order not to make Ali sad, she resolutely chose to leave. In order not to upset Ali, she helped Ali to cheer up as Wei Qing's sister. When all the truth came out, two young people who loved each other came together again.
