Story is set just after 4 Walls promotions ended. Krystal and Amber have one another. With everything happening around them, no Sulli, living up to people's expectations how will they survive with one another.

Can light shine one's dark isolated heart? Can light beam at the sign of heart break? Can light break the impossible? Two lovers, two hearts, but one love. Will everything remain lightless?

Rain tells it's own story. Kikwang loves to be the listener. But Yoseob doesn't like the situation at all. He despises the rain.

  It takes 1 minute to change our lives, It takes 1 minute to love you, It takes 1 minute to change you.

Cuts, Slices, Slashes are all involved in the yearning of love. This depression grows deeper and deeper. But it's something that both Yang Yoseob and Lee Gikwang desire.
