Lee Seo-jin Gets Run Ragged by ALLDAY PROJECT ANNIE on 'Manager Seojin': "Glad I Never Had Kids"

Lee Seo-jin ends up playing doting “uncle” and full-time handler to ALLDAY PROJECT’s ANNIE on SBS’s Friday reality series “Manager Seojin.”

The co-ed group guest-stars on the Nov. 28 episode of “Manager Seojin.”

Assigned ALLDAY PROJECT as their “my star” clients, Lee and Kim Kwang-gyu quickly realized this wouldn’t be a standard handoff. First rule: use English nicknames to keep the hierarchy “flat.” Then came a dedicated carry-on packed with each member’s must-have items―far beyond the duo’s usual light-touch approach.

Still, they found their groove. At a packed ad event, Lee drew on his years of hosting experience to run the floor like a pro, while Kim―fresh off a TikTok challenge boot camp from U-Know YUNHO―flipped into “pro challenge mode,” earning cheers from the members.

Later, completely wiped, Lee cracked, “Honestly, I’m glad I never had kids,” prompting laughs. ANNIE had recently called him “uncle” on YouTube’s “channel fullmoon,” revealing her parents and Lee have been close friends since her high school days―fueling curiosity about their long-standing connection.

The episode teases just how far “Uncle” Lee went to keep ANNIE happy―and the untold stories behind their bond.

Catch Lee and Kim’s ever-improving assistant skills―and their most exhausting day yet―when “Manager Seojin” airs tonight at 11:10 p.m. KST on SBS.
