The tvN variety program 'You Quiz on the Block' will present a variety of love stories on the theme 'Is This Kind of Love Possible?' in its 361st episode, airing on the 23rd at 8:45 p.m. This episode features Charlie Smith, whose parents — Korean mother Park Yu-seon and American soldier father Ralph Smith — found love across borders during the Korean War; Kwon Sun-mi, the 22nd-generation head heir of the Icheon Seo clan's Yanggyeonggong branch, which carries on a 600-year tradition; and actor Shin Hyun-jun, who gained popularity in Peru through the drama 'Stairway to Heaven,' each sharing their own love stories.

■ A cross-border love story that bloomed in the middle of the Korean War

Charlie Smith shares the story of his Korean mother Park Yu-seon and American father Ralph Smith, who met 75 years ago in the middle of the Korean War. The program introduces how the two came to meet, prompted by a request from his mother, who lost her family during the war, along with cinematic episodes from their lives. It will also reveal stories behind a lavish first-birthday party, Ralph Smith's devotion after settling in the United States, and his mother's final recorded words.

■ Head heir Kwon Sun-mi's love and resilience

Kwon Sun-mi presents a daily life unlike the traditional image of a daughter-in-law, riding a motorcycle. She shares why she chose to marry her husband despite his being late to their matchmaking meeting, and stories of the head family's food, which she learned from her mother-in-law and presented as the North Gyeongsang representative at the Hansik Daecheop (Great Korean Food Contest). She also recounts how she overcame hardship by riding motorcycles with her husband, who changed to be like a three-year-old child after suffering sudden cardiac arrest. Kwon Sun-mi said, 'Riding a bike was my breakthrough,' introducing her special daily life with her husband. A busy day at the head family household ahead of Chuseok can also be seen in the broadcast.

■ Shin Hyun-jun, called 'Tae-hwa Oppa' in Peru

Shin Hyun-jun revealed an episode in which he was called 'Tae-hwa Oppa' in Peru thanks to his appearance in 'Stairway to Heaven,' with so many fans gathering that the airport was paralyzed, along with behind-the-scenes stories from fan meetings, his path to becoming an actor, and a special story about his father. He said, 'So many fans showed up that Peru's airport was paralyzed.' In addition, he shares stories about his first meeting with his wife, a cellist 12 years his junior, their long-distance relationship and marriage, and his final moments with his father, who was facing the end of his life.
