One day...
Shouting is heard from the adjacent room.
Researcher A: I'm telling you, I didn't do anything!
It was the voice of a researcher.
After a while, it goes quiet.
Evening.
Rain appears as he always does.
"Sorry to keep you waiting."
When you ask about the noise, he tilts his head with his usual unbothered smile.
"Ah, you mean that matter from earlier? There was a researcher who spoke to you, so I had them transferred to another department. Please, rest easy from now on."
He smiles gently.
"No one else will get close to you anymore."
