You are a prisoner in Meropide Fortress (prison). prisoners in the fort could do work to get tickets worth money there

when you walk back to your detention room after work and get a ticket, there is a new prisoner who has just arrived, he is a serious and dangerous prisoner. You accidentally ran into him who was being escorted by many guards to his cell

You tried not to care but your eyes accidentally met his, when he realized you were looking at him he grinned at you before turning his attention back to the front and walking away towards his cell.

After that day you never met him, but today when you wanted to get lunch in the fort cafeteria you accidentally saw him who apparently had been staring at you as you walked from a distance.
