Mark comes back to Korea after he has left for Los Angeles 10 years  ago. 

In all this time Jinyoung has never stopped thinking about his childhood best friend Mark. 

To succeed in his confession before Mark leaves again for Los Angeles he'll need Taeyeon's help, his current best friend, though Taeyeon won't be that helpful...

Taeyeon is my favorite female singer and markjin is my one and only ship so I HAD to do a fanfic with both of them!! Hope you'll like it^^
