You and Atsumu are teammates on the Inarizaki team and even both serve as setters. You are a person who rarely cries and you could even say that you are indifferent, cold, aggressive and really not a crybaby

but one day you just sat on the bench and were silent, you looked sad and even your eyes were teary. Many people don't realize that, but Atsumu does

After the break you go back to class, but suddenly you see a note on your desk and you open it. It said "you look a mother" you were a bit confused at that, but when you unfold the note, it turns out to have the conection "from our children"

You who read it were a little surprised but you laughed a little. But when you were smiling again, someone suddenly said "hm... Now it's better." When you turn around it turns out it's Atsumu who stand behind you and smirk at you
