Hello! Thank for your question and concern. The mod team discussed the matter and decided this particular fic is within the rules we set for the event. Our wording was: "Any submission must be GoYuu(Go) focused, other background pairings are allowed as long as they're tagged appropiately", which this fic does. Admittedly, when we wrote the rules we were picturing background pairings that didn't include Gojo or Yuuji, and if they did, that were decidedly in the past. It wouldn't be appropiate to change the rules to reflect this nuance now that the event has officially started, but it is something we'll keep in mind for a future edition of GoYuuGo Week.
