A retro arc describes the phase someone goes through when they get fully absorbed in nostalgia culture — rewatching old shows, buying vintage gear, curating a throwback aesthetic across their whole life. It's treated like a character development moment, a narrative shift where someone 'enters' their retro era. Unlike a passing trend, a retro arc implies commitment and a kind of identity transformation. Friends will clock it immediately: suddenly your playlists are all Y2K pop and your apartment looks like a thrift shop exploded in the best way possible.
