Comedian Kim Ji-min posted photos of a housewarming party held at Kim Dae-hee's home on her SNS on the 19th, saying, "Senior Dae-hee's housewarming! Is my sister a chef? The interior is art! I'm jealous!" The photos showed him with acquaintances in a spacious living room.

Kim Dae-hee previously revealed his home through the YouTube channel 'SuperTV' in February.

I'm buried in debt."

Kim Dae-hee married Ji Kyung-sun, a flight attendant six years his junior, in 2006, and they have three daughters. It was reported that their eldest daughter, currently attending Yonsei University, passed the transfer exam and was admitted to a Korean medicine school this year.
