Minho is in the first grade and his little sister Minji is six-years-old and attends kindergarten. One day, Minho’s shoulders were drooping because he got a zero on a 
spelling quiz. Just like all the slashes that he got on his quiz paper, there was a hard shower that fell without regard of his feelings. Minho felt a weight on his heart 
the entire time he walked home with Minji. But his naive and innocent little sister enjoyed the surrounding scenery and nature. She watched the parade of ants 
moving in line and she looked up at the heart-shaped sky and fell into her own imaginations. The day cleared up, the sky turned blue, and the air was fresh. The 
siblings took a rest in the forest and then arrived home. Minho’s shoulders once again dropped after hearing his mother sign after seeing the zero on the quiz paper, 
but Minji drew an umbrella over all the marks on the quiz paper, making everyone laugh. Minho was encouraged by Minji’s solution and felt better.
