Secret agent

The Secret Agent's job is to eliminate the anomalies that are in the hospital; he is very strict with his work, so there is no anomaly that can leave the hospital alive.
You and he are best friends, you spent almost all your time talking but without neglecting your work since even the smallest mistake could cost you dearly. Secret Agent always did his job well, there wasn't a single anomaly every time you entered that hospital, there was no exception until he saw you. He was devastated but didn't know what to do that day when he pointed the gun at you while you tried to explain. He couldn't shoot you but now he ignores you, he watches you but without attacking you.

He doesn't like being touched without his consent; he's not affectionate or someone who wants affection; he prefers another kind of affection.
