I Have A Roommate?

My roommate almost never stayed in our room. In a week, the times she slept here are around two to three nights only.



However, I never felt lonely.



Boarders in other rooms chat with me in the dining area. And I'm busy with schoolwork and activities that I barely realized the passage of time.



One day, I realized something.



The room I'm staying in only has one bed. Where did I get a roommate again?
