From an ex.
About two years ago (approaching), he sent me a play from some pro at the time (can't remember who) and constantly nagged me to play it, even though I had no interest in rhythm games. Then, a while later, we barely talked anymore and one of my conversation starters was, "Hey, what was that game you always wanted me to play with you? You know, the one with the circles?"
He sent me a link to the site, I clicked and made an account :>
