Sudoku Night

We got 1 to 9 and the squares like window shapes

This night still young and boring

How to we stand this time

My friend

We have to fill this blanks

긴긴 밤

밤의 빈 칸을 채울래

We got 1 to 9

And we have to fill this blanks

We got 1 to 9 and the squares like window shapes

This night still young and boring

How to we fight this night

We have no choice

My friend

1 to 9

We got 1 to 9

We just 1 to 9

We just 1 to 9

1 to 9
