About YongSeo
YongSeo (also called the 'Goguma Couple') is the fan pairing between CNBLUE's Jung Yonghwa and Girls' Generation's Seohyun, born from their participation as a virtual couple on MBC's variety show We Got Married, which aired from 2010 into 2011. The nickname 'Goguma Couple' (sweet potato couple) originated from an early episode where Seohyun brought sweet potatoes as a gift, and Yonghwa joked about her healthy food preferences. The endearing nickname stuck and became inseparable from the ship's identity. The two bonded visibly over their shared love of music: Yonghwa as the leader of rock band CNBLUE and Seohyun as a vocalist in the nation's top girl group. They exchanged knitted scarves, wrote and performed music together on the show, and took wedding-concept photos, all of which fans treasured. Even after the WGM arc concluded, the YongSeo fanbase remained active and devoted.
YongSeo is one of the most iconic We Got Married pairings in K-pop history, with a devoted fanbase that has remained active for over a decade. The ship is widely credited with popularizing the 'Goguma' couple concept in K-pop fan culture. Fans are careful to celebrate the chemistry they showed on the show rather than speculating about their private lives.
