This is Recent film: A woman works in a bookstore. An old friend resurfaces. Her friend is a Lesbian and showed romantic interest in her. Her friend tried to kiss the woman on a camping trip and the woman was angry at that time. Her friend is now working for a guy and his Grandfather invented a Time Machine. They find out that the machine kills the user only to send him to be reborn as a baby. The woman realizes at the end that her Boss in the bookstore is now her small child.
I saw this film recently and cannot remember the title. It was a little confusing and I wanted to watch it again.
