Opposite Sides

It's Shigaraki's and Izuku's final battle. Everything settle downs to this.
No one is watching because they're 30 minutes away from the city.
Izuku is going to make the final blow, but he can't do it. He throws away his weapon and lays down with Shigaraki. In their dying moments they talk to each other and find more about the other person and realized how similar their pasts are. They found someone that understood them.
But the inevitable happens.
"Why is life so unfair? We could have become great friends...Why did we end up on opposite sides, *cough cough cough* Izuku?"
(Also I wanted to say um...I remember seeing something similar and if it's exactly the same well can someone tell me who the creator is. Cause I don't want to get in trouble if I don't tag them, but I'm pretty sure this is original)
