The eldest son of Park Hae-mi was revealed.

On the 22nd, during the broadcast of MBC Every1 and MBN's 'You're All Grown Up but You Don't Go Out,' Park Hae-mi's eldest son and stepsibling of Hwang Sung-jae, Lim Sung-min, made an appearance.

Hwang Sung-jae remarked while looking at his older brother Lim Sung-min, "You're truly a cheat character," saying, "You are a scholarship student from Seoul National University, good-looking, and very fun to be with." In response, Park Hae-mi also noted, "Sung-min sings incredibly well," adding, "Honestly, he should have been a musical actor."

Park Hae-mi said, "There are many kids who sing like this and look like this," noting, "There are really many kids who are working hard. He is comfortable because he has Park Hae-mi behind him but doesn't know much about the world. If he weren't my son, it wouldn't have happened like this."

When he heard this, Hwang Sung-jae was upset and abruptly stood up and walked down to escape. Park Hae-mi remarked, "Sung-jae is easily swayed by what he hears," adding, "You're an actor, so why would you say such things? When you hear these stories, you don't respond. And you shut your ears to what your mother says. I don't understand why he worries about his image when there's nothing to consume."

Park Hae-mi stated, "It's chaotic and difficult, but when such nonsense is spoken, this kind of comment comes out as well. You should experience hardship once; that's the kind of feeling that arises."

Lim Sung-min advised, "If you come at him like that, would he want to listen? If you speak with facts, he becomes more resistant and doesn't want to hear it."

Park Hae-mi expressed, "I am not wise. I need you to help me a lot." Lim Sung-min replied, "He needs to be made to ask for help. You're right, but just help him this once. This is how it should be." However, Park Hae-mi countered, "Why should I have to ask for help?"

Lim Sung-min remarked, "Will you be persuasive if you fight with pride?" stating, "I understand more as I raise children. The child knows his mistakes. He wants to change, but if I interfere at this point, he will cry. In fact, adults are the same way." Lim Sung-min commented, "Mother makes decisions without warning."
