For the first time in the 28th season of "I am SOLO," a divorced couple announced their pregnancy with a second child. On the 15th episode of the variety show "I am SOLO," aired on SBS Plus and ENA, an ultrasound video of the baby from Solo Nation 28 was revealed. This scene shocked the three MCs: Defconn, Lee Yi-kyung, and Song Hae-na.

During the broadcast, the second-choice dates of the 28th season's single men took place. Young-sook chose Young-soo and Kwang-soo as her first and second choices, respectively, and went on a 2:1 date with the two men. Young-sook asked Young-soo, "Do you have feelings for Hyun-sook too?" but Young-soo avoided giving a direct answer. Young-sook expressed dissatisfaction, saying to Young-soo, "It feels like you're talking down to all seven women. It doesn't look good." Young-soo countered, "I just talked to Ok-soon and Hyun-sook for the first time today. How can I make a decision when it's the first time?"

In the awkward atmosphere, Young-sook questioned Young-soo's open-mindedness. When asked, "Are you speaking as if you understand the situation fully even though you've never raised a child?" Young-soo admitted his shortcomings, saying, "I think I was short-sighted." Later, in an interview with the production team, Young-soo said, "I don't have children, so I don't think I can deeply empathize with Young-sook's feelings."

After finishing the date with the two men, Young-sook tearfully said, "I think I have to give up my feelings for Kwang-soo. When I looked back at myself, it was Young-soo." On the other hand, after his date with Young-sook, Kwang-soo called Jeong-hee. Jeong-hee asked Young-sook, "Did you tell Kwang-soo about my feelings?" Realizing her mistake, Young-sook teared up and apologized, saying, "I made a big mistake. I'm sorry."

When Jeong-hee asked, "Have you sorted out your feelings?" she repeatedly answered, "I don't know," showing her confusion. Kwang-soo expressed his intention to move forward, saying, "I think I've sorted it out," and created excitement through the first-place mission in the Yutnori game, "Holding Hands and Saying 'Honey'." In an interview with the production team, Jeong-hee declared, "Young-ho is gone from my heart," and announced her intention to pursue Kwang-soo.

The next morning, Soon-ja revealed that she had feelings for Sang-cheol but was hesitating because of Hyun-sook. Ok-soon advised Soon-ja, "Hyun-sook has sorted out both Sang-cheol and Young-soo." Soon-ja immediately went to the common living room and sat next to Sang-cheol, but Young-sik approached and requested a one-on-one conversation. Young-sik said, "Since the first impression choice, I have consistently chosen only Soon-ja. Am I within your boundaries?" Soon-ja had never had feelings for Young-sik but told a white lie, saying, "I have always been concerned about you."

The production team informed the three MCs about the birth of the divorced special baby, causing a stir on set. The ultrasound video of the 28th season baby, Na-sol, born during the 28th season, was revealed. Defconn speculated, "Hearing the heartbeat in the ultrasound, is this the child of Kyung-soo, who has been built up by 30 years of exercise?" Lee Yi-kyung guessed, "Could it be that Kwang-soo and Jeong-hee have possibly borne a child?"

The pregnancy news from the 28th season of "I am SOLO" has captured viewers' attention. After the broadcast, the MCs congratulated, saying, "Something miraculous has happened in Solo Nation." Defconn could not hide his excitement, saying, "They say a baby has been conceived," while Song Hae-na expressed curiosity, asking, "Who?" The MCs continued to speculate about various individuals such as Ok-soon, Jeong-hee, Kwang-soo, and Young-ho.

This broadcast marked a new turning point for "I am SOLO," drawing great attention from viewers. Curiosity is growing about who the parents of the 28th season baby, Na-sol, are. The show is providing new entertainment to viewers through the stories of couples who have borne fruit.
