Hi all,
A quick PSA. Recently I have rolled back several edits adding Chizuru and Arata as each other's girlfriend and boyfriend on the Relatives section of their respective infoboxes.
Thanks to all of you for your efforts to improve the wiki. However, as happy as we are about that state of affairs, mentioning it under relatives is incorrect. Relatives are connected by blood or marriage, so your girlfriend or boyfriend is not your relative (unless they're also your blood relative, but let's not open that particular can of worms).
This is also why unlike with Chizuru and Arata, it is correct to have Rena and Kazuomi listed under each other's relatives. As we know, they are married as of Volume 15 Bonus Report 1 (chapter 222.5 part 1).
There also is no express mention about Chizuru and Arata having gotten married before Rena and Kazuomi's wedding took place. The only panel in the entire chapter with either Chizuru's or Arata's left hand unobscured shows Arata without a ring. Admittedly that panel shows him at his desk at the office, so it is possible that it's intended to be inconclusive as he might just not be wearing his ring. Nevertheless, nothing we know points to them having gotten married, so that's what we must assume.
