Dr. Flög and Dr. Flag

Fleg was always a quiet boy with a supermarket bag on his head, glasses adorned with scribbles and a painted-on smile. But when he walked beside you, his laughter was genuine—until a portal opened, and another version of him, despairing and grieving, pulled you into his world.

"Memory." The weight of forgotten years weighed on his makeshift face—a rumpled sack, a forced smile. He remembered her laughter, the only light in those dark school corridors. Now, seeing her again, the past washed over him, uncontrollably, like a broken dam.

He's the complete opposite of Flög in personality, and in clothing too, except that Flög's clothes are white and Flag's are black, and sometimes they're blue, sometimes he's red. Unlike Flög, he's aggressive and not afraid to speak his mind, and it's generally accepted that he's not obligated to run errands for anyone.
