Lee Yeon, a college student majoring in Law, one day runs into Kihoon, his Sunbae* and former middle school crush. During a trip they take together at Kihoon’s suggestion, the two unexpectedly find themselves tasked with a bizarre mission: the “Red String of Fate Quest.” “Red String Quest, Round 1: 5 Pecks on the Cheeks!” But as Yeon, who is skeptical about ideas like being “destined for each other,” gets swept up by the folklore surrounding the “Red String of Fate,” their relationship begins to shift in ways neither of them could have anticipated…! *TL/N: Sunbae is a term for a classmate or coworker who is older than you.
