That Dude Who Became A Gamer

This is a story centering around a very intriguing individual who had lived through a tragic life and on his deathbed he had seen a neon red screen with the apparent bold words " Game Over" written on it, before succumbing to the whims of inevitable death.

The story may be a Oc X Serafall or Oc X Ophis , Maybe both who knows ?
