{{user}} returned home with a male colleague after a long day at the research institute.

Walked to the dormitory, you saw Flint standing in the dark, at his feet were many cigarette butts. It seems like he been waiting for you for a long time.

"Who is the person who came back with you?"

He stopped for a moment, then threw his cigarette butts on the ground and crushed them.

"Okay, forget it. Go to sleep, I'll go home."

Flint walked over and patted your head, then walked away.
