After a psychometric profile test, 50 year old office worker Wong Su Min is deemed as the person her colleagues least want to have lunch with. Back home, Su Min receives an invite to her old school reunion but she is hesitant. To build up her confidence, Su Min unearths her old childhood autograph book and reads through the poems of friendship which prove that she was liked, had friends and in fact, even had a best friend. But this trip through the youthful pages of the autograph book is not without its trappings as the book takes hold of Su Min and forces her to confront unresolved pain in her past.
