JTBC's variety show 'Love War' will reveal the intense conflict of its 'oldest-ever couple' in episode 20, airing at 9:50 p.m. on the 9th. In this episode, Girls' Generation's Yuri joins as a special diplomat, and a 49-year-old woman and a 40-year-old man appear as a couple.

The two are an older woman-younger man couple with a 9-year age gap who have been dating for nine years. The man is Korea's top fire-show performer, nicknamed the 'Spirit of Fire,' while the woman's strong personality left a deep impression on the cast and the studio.

During the broadcast, the female cast member poured out constant criticism, anger, and harsh words at the man. At one remark from him, she raised her voice, saying, 'Am I crazy?' and then expressed her anger, snapping, 'Don't you talk down to me and nitpick my tone!'

Watching the scene, Lee Hyo-ri could not continue her words, saying, 'It seems like this older sister can't be beaten.' Seo Jang-hoon commented on the woman's behavior, saying, 'This is not something to get this angry about,' adding, 'It seems like her patience circuit has broken.' However, the woman stood by her position and did not back down even against Seo Jang-hoon's criticism, and in the end, Seo Jang-hoon said, 'Setting aside the story between the two, the girlfriend's behavior is far too rude.'

'Love War,' starring Lee Hyo-ri, Seo Jang-hoon, and Kim Hee-chul, is a reality program that follows couples deciding whether to break up or stay together. In this episode, a tension-filled conflict between a 'fiery woman' and a 'fire-breathing man' couple will unfold. The final episode of 'Love War' Season 1 airs on JTBC at 9:50 p.m. on the 9th.
