In my opinion, 'sweet scar' is the continuation of 'snowy kiss'. The pv really gives me the feeling, like she's gone through a tough time and at the end, is finally able to move on.

She's back home, trying to figure out what she should do next. The smiling scenes give me the feeling, that she's remembering her vacation with 'unknown guy' and Maro. She remembers all the fun they had, reliving the moment.. Then she remembers the fights they had, the bad words and breaking up. She's lost, sad, doesn't know where exactly she stands and finally decides to move on. (The canvas she painted on is finally finished and there's nothing else to do.)
With going out of the door, she cloeses that chapter in her life and moves on.

My 2 cents..
