When 21-year-old college junior Noah Reyes wakes up trapped in a midnight retake exam, he quickly learns the rules: break a rule, fail a test, or leave without permission—and you receive an F. An F doesn't just mean failing. It means being wrapped in exam paper and erased from existence entirely.
The Love Survival System activates, assigning Noah his only way out: romance Professor Lucian Vale, the substitute examiner who controls every grade and every life in the room. There's just one problem—Lucian is an S-class anomalous entity, a being who can write F's into existence with a single black pen.
What begins as a calculated survival strategy—stealing the pen, trading kisses for points, exploiting every loophole in the rules—slowly becomes something real. Noah sees the man beneath the monster: a former student who failed once and was transformed into the very thing that destroyed him. Lucian, in turn, finds himself breaking his own rules to protect the one student who refuses to be afraid of him.
