Were they lovers? Worse. You can run from the past, but you can't run from fate. Inseparable at first, until life pulled them apart and turned them into strangers. Time changes everything, especially people, and for a while, they existed on two parallel tracks. But when a series of impossible events forces their lives to intertwine once again, Steve Harrington and Y/N soon realise that the person they lost is the only one who can save them. From unwilling allies to sharp-tongued rivals and back again, their so-called irreparable history is about to prove that some people are simply meant to collide.
