Kyungsu and Oksun from the 22nd season appeared on tvN's 'Kim Chang-ok Show 4' and shared their realistic concerns after remarriage. The two met on 'I am SOLO,' registered their marriage in May, and held their wedding ceremony in November. On the show, Oksun expressed concern that her son believes Kyungsu is his biological father. Oksun said, "My son asks, 'Mom, is she my mom? Dad is my dad, right? Then what about the sister (Kyungsu's daughter)?'"

Oksun also talked about Kyungsu's daughter not calling her mom. She said, "My husband's daughter is 11 years old and at an age where puberty is coming, so I am cautious," and added, "While I am very happy that Kyungsu has formed a family, my feelings are different." Additionally, Oksun shared, "Kyungsu was waiting with my son in front of the daughter's academy," and "The daughter still doesn't know how to introduce my son."

Oksun emphasized, "My relationship with my son is different. My son has never seen his biological father and has no contact with him. But the daughter knows her mom," and added, "I don't intend to make her call me mom. Even if she calls me aunt until the end, as long as I am her guardian, that's enough." She also said, "Kyungsu makes me strongly feel, 'You are coming into my family.'"

In response, Kyungsu said, "It's easier because my son has no memories of his biological father. After meeting two or three times, he called me dad." He added, "At first, when the two met, I thought it was fine if he called me aunt for life, but after living together, I think it would be better if he called me mom."

Kim Chang-ok mentioned that there can be wounds in the process of two families becoming one, saying, "It's hard to try to plant the roots of me and my child in a different place. If you do well and then suddenly leave, it would be hard to recover," speaking on behalf of Oksun's position.

Kyungsu confessed about his anxiety, "I divorced due to infidelity during my marriage with my ex-wife." He said, "After getting married, I was busy working and had many late nights. I felt like I couldn't take care of her. So when I met someone else, I felt like I had to do everything for her, and I thought that was my way of protecting her."

Oksun and Kyungsu appeared on SBS Plus and ENA's 'I am SOLO' special for divorced singles and succeeded in remarriage. They are raising a son and a daughter respectively and started anew as a family of four after remarriage. Through the broadcast, they honestly shared their concerns and thoughts, gaining empathy from viewers.
