'Efficient Meetings for Singles' finds Park Sung-hoon deciding to get a matching couple ring for Han Ji-min.
On the April 5 broadcast on JTBC, Song Tae-seop (Park Sung-hoon) is inspired by the couple rings he notices among the participants — including Shim Sae-byeok (Kim So-hye) — and heads to a workshop to arrange a matching ring for Lee Ui-young (Han Ji-min).
When the shop owner asks for the ring size, Song Tae-seop answers, "I don't know the size—what should I do?" The owner suggests, "Ask her for the size or bring a ring she wears often." Song Tae-seop half-jokes, "Should I steal one?" and appears visibly flummoxed.
Determined to find Lee Ui-young's ring size, Song Tae-seop looks for opportunities to check. He repeatedly handles her fingers in an attempt to gauge the size, but a clear chance never presents itself.
Meanwhile, Lee Ui-young's boss, Eun Jeong-seok (Kim Won-hae), calls to say that her friend, who is getting married soon, had asked about the cancellation fee. Lee decides to contact her friend and goes to the friend's dress fitting.
