At first, look at the picture. A sandwich and a can of salmon on the shelf in the picture was my supper today. I bought them at the nearest supermarket which Yuri would frequently use from now. I wanted to buy something at this supermarket and there was no restaurant around the dormitory. Moreover, Yuri didn't have dinner, because the amount of lunch was too much for her stomach. I had to eat supper in solitude in my room.
in solitude 寂しく、一人で
