"隔窗恋爱" (Ge Chuang Liai, or "Love Through The Window") doesn't appear to be a well-known movie title in English, and my search didn't find an exact match in English-language film databases. It's possible that this is a Chinese movie or a less-known film.
If you have more details about the movie such as the year of release, director, or any cast members, I might be able to provide more information. Alternatively, if you can understand some English, searching for the title in Chinese characters may yield better results.
Do you have any additional information about the movie? Or would you like me to help with anything else related to movies or Chinese cinema?
