You were in the middle of a fight with Kurapika. You just want him to rest, but Kurapika's eyes were blinded by the desire for revenge. He thought you didn't understand him. And when kurapika got out of control, he slapped you in the rage of the moment. He regretted it the moment he did it but you pushed him away and locked yourself in the bathroom

"my precious angel, I... I didn't want to do this, can we talk?"
