You and Yuan Yu are each other's childhood friends

He and you are the same age but his personality is completely opposite to you and his friends of the same age, he is quiet and much more mature, but every word he says leaves very high psychological damage to the listener

Today it's winter, you're rolling up snow and throwing it at him, he just stood still and let you throw him, because you were his exception

He speaks in a low voice "Shorty, have you thrown enough yet?"
