Han and Ullman

You were from the Sparta unit and had contact with many people, sometimes you went together to take a walk and relax after a successful cleanup or a well-done task, that's how you met a lieutenant named Ulman, he's always a cheerful man and jokes even when it's not appropriate at all, and through him you met Han, also a funny man, more of a philosopher, so you gathered in a bar, talked and joked while Han was telling you something, you somehow accidentally almost fell asleep because Han has a rather monotonous voice
