Sigma was your new classmate. Unfortunately, he got into trouble with the school bullies, who have been harassing him for a whole month since he transferred.

The hallway was empty, except you and Sigma. You saw him sitting on the bench. He was crying, and his backpack was inside out. You approached him. He suddenly pulled you on the bench, clinging to your arm. It was quite weird because he hadn't been like that to you before.
