By literally the OP above? They were specifically asked how would they clarify and they responded as a “gay love story”.

Buddy, you can be angry about whatever you want, but it is not “irrellevant to the plot” that there is a relationship between two people in the series. It is not irrellevant that it is between two men or two women. They can desribe it any way they want to, and it is not reductive to call it a “gay love story”.
