Super Junior Heechul Kim reveals Yuri's love history of Girls' Generation

Girls' Generation's Yuri is teaming up with longtime friend Kim Hee-chul to dig into each other's dating histories on JTBC's new reality show "Love War."

The show premieres June 23 at 8:50 p.m. KST. "Love War" follows couples on the edge of breaking up and brings in three hosts to help them decide whether to stay together or call it off. Lee Hyori, Seo Jang-hoon, and Kim Hee-chul serve as the dating mentor MCs.

Yuri appears as a special guest on the first episode. Kim Hee-chul, who has known her for 25 years, wastes no time turning the spotlight on her past relationships.

"I've never seen any of Yuri's exes talk badly about her," Kim Hee-chul says, hinting at stories from her dating life. Yuri plays it cool with a quick "Who are you even talking about?" But Kim Hee-chul presses on, dropping a knowing "That guy, you know the one," and seems to point to a specific person, leaving Yuri visibly sweating.

Yuri has plenty of material of her own. She calls herself "a living witness who knows everything from Hee-chul's trainee days," flashing a meaningful look. Lee Hyori jumps in to back her up. "Perfect. Let's strip Hee-chul down today," she says, joining forces with Yuri to go after Kim Hee-chul's dating past.

Yuri also brings sharp advice to the couples on the show. Faced with the story of a personal trainer working 17-hour days and his freelance announcer girlfriend, she reportedly fires back with blunt lines like "Break up right now" and "If that's how it's going to be, just hire someone."
