Tawee Pope (1994)

Maneejan finds out that she can travel to the past through a mirror she bought at an antique shop. That mirror brings her to the place of Khun Luang Akarathep Warakorn, a government official who lived over a hundred years ago. The more times she travels to the past, the more feeling she and Khun Luang develop for each other. She eventually needs to decide whether to reside with the man she loves in the past or to go back to the future to continue living her life with her family and friends.
