On March 21, Gummy and MAMAMOO guested on SBS Power FM's 'Cultwo Show.' During the radio show, one listener shared that they saw Gummy and Jo Jung Suk together on an airplane.
To this, Gummy revealed she went to Iceland with her husband and said, "We recently went on an overseas trip together for the first time because we didn't go on a honeymoon."
DJ Kim Tae Gyun commented, "Jo Jung Suk went to Iceland for a show and he said it was great and wanted to go with his wife again." Gummy replied, "It was really great. I strongly recommend it," and said, "We couldn't see the aurora (northern lights) but the nature/landscape itself was great."
