Regarding this moment, some even jokingly commented that it was "historic".
The reason why their meet-up was so special was because the three guys were all Kim So Yeon's husbands.
Lee Sang Woo is her real husband, Um Ki-joon is her character Chun Seo-jin's husband and Yoon Jong-hoon is Chun Seo-jin's ex-husband.

Then, Lee Sang Woo unexpectedly joined them to say hi prior to his cameo appearance in the drama.
Upon seeing Lee Sang Woo entering the set of 'The Penthouse 2: War in Life', Um Ki-joon and Yoon Jong-hoon burst out laughing at an odd situation.

Um Ki-joon responded with an awkward smile, "I'm somehow losing all my confidence as her husband in the drama since her real husband is here."
After Lee Sang Woo left to get ready for his appearance, Kim So Yeon said, "Gosh, I feel so shy for some reason."
