Winnie, a workplace manager, uses the pseudonym "Stone Pot Bibimbap" to engage in a year-long online romance with an anonymous netizen named "Good Girl," without ever exchanging identities. Seeing her boss Neil wearing the same mug and knitwear, coupled with ambiguous phone conversations, leads Winnie to mistakenly believe Neil is her online boyfriend, resulting in an angry block on him. After connecting with investor Carl, who caters to her every whim—taking her to a pre-arranged amusement park and monitoring her social media activity—various details begin to sway Winnie's feelings. Subsequent interactions in Westwind Town, with a series of coincidences, lead Neil to reveal that he was merely buying the same items because they were trendy, finally revealing Carl to be "Good Girl." With the misunderstanding cleared up, the two confess their feelings and ultimately become a couple.
