Jang Yun-jeong's daughter Ha-yeong makes a surprise appearance in the studio. In the 31st episode of MBC's ⁇ the water-crossed Fathers ⁇ (directed by Lim Chan), which will air on May 7, Jang Yun-jeong asks related expert Kim Ji-yoon for advice on how to help a child who is unfamiliar. In the meantime, Ha-yeong, a child who is unfamiliar with the scene, reveals the fact that he is together. Also on the show, New Zealand CEO Father Jacob hosts the Street Spring Festival with his son Jude and daughter Claire Dearing, intriguing to see what the children in front of so many people will look like. New Zealand CEO Father Jacob and his children boasted extraordinary YG Entertainment and execution power. In particular, his 11-year-old son, Jude, planned an English tutoring project based on the economic ideas he learned from his Father, and the whole family gathered topics in practice. This time, the Jacob family plans a spring festival where they can play saxophone, share things, and play chess games with a variety of people on the street. The Jacob family meets their special uncle Frank, who is a saxophonist and university professor and has a relationship with Jacob at the wedding ceremony. Frank is planning to rob the world of his relationship with global singer-songwriter Damian Rice, who called OST of the movie "Closer". The Jacob family receives street event tips from Frank, who often busks on the streets, and goes through The Speech one by one for the event. At this time, Jacob respects the opinions of Jude and Claire Dearing and helps children to enjoy YG Entertainment and The Speech.
