Bro's life is so empty

Heiner literally has nothing....
Other than the obsession he had/has with Annette, and the traumatic child soldier life he was forced into, he doesn't have anything else.
Man has no hobbies, very little friends, no joy, no personal goals or wishes. Sticking in the military honestly isn't helping him either. He has little time for growth in these areas.

Bro needs to retire, and find himself a life. Because if theoretically, Annette dies and Pandania is defeated, what does he have left? Like, what would he do with himself?
