Love Gauge: 999

Ara Lune, a reincarnated commoner extra at the Empire's elite magic academy, survives by staying unnoticed and ignoring her useless Support System. Then Kael Veyr, the strikingly handsome and dangerous academy prince destined to become the villain who ends the world, transfers into her class, and her system malfunctions with an impossible reading: his affection for her sits at 999 out of 100. Kael insists she once promised never to leave him, carries a relic from a past life Ara cannot remember, and forces his way into every corner of the small, careful life she has built. As rumors, manipulation, and a fake engagement tighten around her, Ara starts to suspect the frightening villain may not be chasing her because of fate. He may have broken fate a hundred times over just to keep her alive.
