Akira was surprised by the weird question. Of course he would not hit Roku. Sure, they were yelling at each other sometimes but he wouldn't get violent with him. Akira shook his head to answer Hiyoko. He too started to realize that talking to Hiyoko like this could mean trouble if someone saw. "I should go back," he said. He assumed that he would just be able to open the door to Roku's appartment because he didn't know about the auto-lock. Hiyoko would know about that though. She could even let him in with her landlady keys, but she could also use this situation to her own advantage to play a little trick on Roku.
