they can have a chapter that Kei will ask Hikari if she wants to go to the place where his family is staying then maybe Hikari will doubt about it cause his dad promised to her that she won't leave until she beats Kei, that made her challenge Kei all day long so she could beat him then the chapter could end in either Hikari won't approve to Kei's offer to her and Kei would find a way to let them have communication to each other or maybe he could get them handphones , or its the other way around ( Hikari will aprrove to Kei's offer)
