Two boys, one older than the other, usually assisted each other in battles, as they worked together in the same job. One of them was very kind and optimistic, and the other violent and pessimistic. 

Because of their contrasting personalities, things got heated between them. Eventually, both of them began hating each other. 

They lashed out at each other at moments where one pissed the other off. The kind boy became easily irritated, and the violent one became much more brutal.

Eventually, they had enough. Their rivalry became a full-blown battle. One boy challenged the other to a battle and they fought. 

Timothy, the irritated boy, spent the entire time attempting to defend himself from his enemy. Andrew, the violent one, was focused on trying to tear Timothy apart. He actually almost cut his throat open. But what happened?? Sae-Young, a bystander, shot Andrew before he could do anything to Timothy.
