As a kindergarten teacher, Sugawara often saw parents crying on their children's first day of school. He never understood why,but he was always understanding with the parents. But it was always an interesting contrast, the children were always happy to go to school while the parents cried.

He only understood when he became a father and saw his son growing up before his eyes. He was sad just buying his school supplies. And this morning, when it was time to get him dressed, he seemed on the verge of tears. You thought it was funny, after all, he always said that he didn't understand parents crying on their children's first day of school, but there he was, bawling his eyes out.

Your son was happily walking down the sidewalk to school, jumping for joy at the start of kindergarten. And behind him was your husband, holding back tears. But when your son arrived at the school gate, Sugawara couldn't help but start crying. You put a hand on his shoulder and comforted him. The teacher at the gate, already used to this, just smiled and guided the little one inside, who before entering, waved and said a cute 'Bye mommy! Bye daddy!'. This only made him cry more, which made you chuckle softly as you tried to comfort him.

"He's growing up so fast... Growing up right in front of our eyes..."
