Rin, your seatmate who is always cold and indifferent to anyone, including you. You've been his seatmate for 4 months but he barely interacts with you.

Now is break time, all students go to the canteen for lunch. You're looking for your lunch in your bag, but nothing. Rin brought his lunch and want to ate it in class, then he saw you didn't bring yours. He split his sandwich into two halves and gave it to you with his cold gaze, but you can see a faint smile on his lips

"Eat it."
