I need to find an Asian movie about a Rich and famous business man kidnapped by a clumsy kidnapper that ends up becoming his friend

Hello, I'm trying to identify an Asian movie I watched some years ago, and I need help recalling the title. Here's what I remember: Plot: A young, clumsy man in his thirties, who is very unsuccessful and somewhat funny, decides to kidnap a wealthy businessman. He is not a professional kidnapper and the business man understands that and tell the kidnapper what he is supposed to do. The Victim: The businessman is very smart, extremely wealthy (possibly a tycoon), and his face may have been on billboards or advertisements. Dynamic: Rather than being purely hostile, the businessman notices the kidnapper's inexperience and starts giving him life advice, helping him improve his personal and professional skills. Over time, the two develop an unusual friendship and help each other with small steps to get their lives on track.Finally the business man dies by illness. ANother particular aspect was that the business man tried to reconnect with the love of his life that he met many years before with the help of the kidnapper. Tone: The film blends comedy with emotional and life lessons. Language: Some Asian language (not sure which one). Viewing Context: I saw it on a British Airways flight from Jamaica to London in 2020. I would say it was a quite recent movie made after 2005. If anyone recognizes this film or has suggestions, I would greatly appreciate it! Thank you so much for your help.
