"What my mind may not remember, my heart always will." – Fading Memories by Chris Mathieu.

Seohyun, a young musical actress, was involved in a tragic car accident while on her way to the rehearsal and suffered partial memory loss. She could not recall the recent past that was acquired after she moved to Seoul six years ago. In order to retrieve her memories back, she packed her stuff and traveled to Busan to meet her boyfriend, Yonghwa. Meanwhile, the said boyfriend was in his wedding preparation to another woman in the next six months.

Why would Yonghwa do that? Was there something happened between them that Seohyun didn’t remember? How would Seohyun react to it?
