Two friends, one summer, and a calculated risk.

Kim Haerin has 300 hours to accomplish her internship program and Oh Sehun has zero patience.

When Sehun feels his marriage falling apart, he starts to question whether or not it was right to pick up where they left off. Ideally, married couples should want to grow old together, not grow apart. But the latter seems to be making itself too obvious when the couple can no longer deny the wall standing tall between them.

A story of when love threw them into a situation and wondered if they should bend or break.

          He chose her yesterday, He's choosing her today, will he still choose her 

Oh Sehun found it hard to move on after losing his first love from Pancreatic cancer on a cold December morning. Ever since, nobody could go through the walls he built around him once again. He used to have these walls, separating himself from everyone, always cold and didn't really bother about anything else until his first love--Shin Youngmin--came to his life. Now that she's dead and gone, Sehun went back to his usual self--even

Christmas time. A cold lonely Christmas time for Sehun.
