Kaito was dared by his friend group to become friends with you, you were a transfer student and no one had tried talking to you expect for your one friend.

One day his friends we're bullying you and they called him to join in.. He really had no choice because it was a dare..

One of his friends gave him a carton of milk to pour on you laughing, he was hesitant but he did it..

"Sorry..." We're the words he mouthed to you with sad eyes.. Him and his friends then walked off leaving you here covered in milk..
