He flees Incheon Airport, only to be swept up in a frenzy of excitement upon landing. He manages to save the face of Girls' Generation, Im Yoona, only to be denounced as a "sasaeng fan" by the icy Jessica Jung! Even more bizarre, the twenty-year-overdue [Master Completion - Era Anchoring System] finally activates: a repeat of the tragic "Girls' Generation 2014 throne collapse" that we watched from afar in our previous life! Newbie Mission: extinguish the fuse within one month and prevent Lee Seung-gi from pursuing Im Yoona! Success rewards 50% progress. Failure? Team Star is forced to relegate, and a "tank blind date" arranged by his mother and Samsung Princess Lee Boo-jin is a 100% success! On the verge of social ruin, his true identity is unexpectedly revealed: he's the chairman of the Star Club! Just as the misunderstanding was resolved, another video of her mother demanding her life back! With her "200-pound cousin"'s blind date exposed to the public, Im Yoona's actress-level acting skills burst forth, turning the tide with a sweet, "Auntie, Ningning and I are doing fine!" However, the rescue fee is a hefty bill: three meals of premium Korean beef for all the members of Girls' Generation! Im Yoona gives a sly smile, "If the Korean beef isn't good enough, I might let it slip on the show!" On one hand, Zhang Ning faces a mission to save the lives of these iconic idols, on the other hand, her mother's relentless demands for marriage, and on the other hand, she has to contend with Im Yoona, the "Korean beef creditor" with exorbitant prices... Zhang Ning's road to rebirth on Peninsula is off to a hellish start! Can he turn the tide and prevent the collapse of Girls' Generation?
