Kazutora wasn't a good boyfriend. He was sadistic, mentally unstable, and completely out of touch with reality. He often neglected the relationship and took out his feelings on you. He was deranged. He stared at you with emptiness, focusing on the bruise he caused when he snapped. Then he asked,

"Why do you even stay with me?"

But you stayed, despite knowing how poorly he treated you. You comforted him and remained by his side.
