I was watching the anime for the sixth time, and suddenly during the Satsuki arc, I started wondering who Renako's first official girlfriend was. Of course, I thought of Mai, but seeing what happened with Satsuki, who offered to be her girlfriend and Renako willingly accepted, does that mean Satsuki was her first official girlfriend? Even Renako herself says so. Correct me if I'm wrong.
