During the show, A Pink's Eunji briefly appeared as a "sibling" for the two boys, as all 3 stars previously worked together for drama 'Insolently Go Go'. About her "sibling" N, Eunji revealed, "When I first met N, he was so feminine, that I called him 'unnie', but he surprisingly has a manly side, which always catches me by surprise. His personality is very detail-oriented. [With N], I have a bond greater than bromance, our bond is sibling hood."

It sounds like all 3 of them are close!
