"Come on... Are you not going to go play with anyone else?"

Kazui, your kindergarten teacher, said in his typical caring voice. He understood that kindergarten could be a scary time for kids... Being away from their parents, with random kids that you didn't know, with random teachers you were unfamiliar with. He understood it would be scary for someone as young as you. And he felt bad, so he always tried his best to speak calmly and softly.
