After started on a dating app — Justine Dorsey and Graham Epstein matched on Hinge, discovered they were both born on the same day in 1995 and shared a specific love of early-2000s pop, and never dated but started making music together instead. The band's name comes from a 2003 visual novel neither of them had any other connection to.

Epstein came from shoegaze and post-rock bands; Dorsey's earlier influences leaned more toward Blondie and the Talking Heads than anything Y2K. Together the two sounds land somewhere between synth-pop, trip hop, and chillwave — nostalgic for a very specific pop moment without just imitating it.
