Where a girl named Yujin had tried to stop falling in love because she didn't want to make the same mistakes like in the past. But, until she met someone new, who actually cared for her, loved her, showed her kindness towards her, showed her what it's like...to fall in love again.

Two figure skaters who has feelings for each other after a long time. Questioning if she’s her or if he’s him.  They’re both confused.  Will they ever talk about what happened 10 years ago or stay silent.  OR...

Only if you fall inlove, you could see everthing clearly.  If you haven't fell inlove then you'll just see black, white and gray.
