Rin had kept his eye on you at school for a long time. He didn't know what this feeling was when he saw you but he yearned for you, he wanted you to be his and only his. He bullied you so he could have an excuse to talk to you. One day he saw you talking with his brother Itoshi Sae outside of school and he was hit by a wave of jealousy. He moved instinctively and grabbed your wrist tightly.

"what are you doing with my brother here?" he asked in a jealous and menacing tone.
