After transmigrating, Lin Qi draws three traits: [Read, Don't Reply] [Schrodinger's Bento] [If You Fail the Exams, Join the Expedition]. The trigger condition for the golden trait turns out to be "fail the exam first." He applies for a janitor job at the Demon King's castle, then uses an anti-gravity sliding tackle to sweep a table straight into the Demon King's bedroom. On the spot, he's hired as an "emotional stability monitor."
The witch Viola is ordered to investigate him. Lin Qi turns around and applies for the position of "person under investigation," with Viola herself as the interviewer. She freezes for three seconds. "You've been rejected." Lin Qi grins. "Thanks, that meets the trigger condition." An expedition team appears out of nowhere, throwing her magic circle into chaos.
The more Viola investigates, the more she realizes that every time this guy uses a golden trait, he loses a piece of his memory.
