Forget Me Not

Rianne has lost her memory of the past two years due to an accident, but letters from a mysterious "Sparks" -- found in a pile of unread mail at home -- have been helping her cope. The letters tell her of a couple's love story, making her hope to find the same unconditional love someday.
Rebuilding her life has been a mess though: her guy best friend is claiming to have been her boyfriend that time, but she seems more at ease with a mysterious stranger. Does she trust the past she can't remember, or take a chance with a more uncertain future?
