What’s Happening in Episode 6?

Three Sisters, One Blowout

“In Your Radiant Season” tells the romance of Song Ha Ran (Lee Sung Kyung) — a woman frozen in a perpetual emotional winter — and the warm, carefree Sunwoo Chan (Chae Jong Hyeop). But episode 6 shifts the spotlight onto a spectacular three-way sister argument that feels achingly real.

Each sister is dealing with her own quiet storm. Ha Ran is sleep-deprived and spiraling after Sunwoo Chan vanished to the United States without a single message before their date. Ha Young (Han Ji Hyeon) is seething after an unexpected cold reaction from her love interest Yeon Tae Seok. And youngest sister Ha Dam (Oh Ye Ju) just had a blowout fight with her boyfriend Cha Yoo Kyum, who’s been inexplicably avoiding her.

Three women, three wounds, one household — and the result is the kind of raw, unfiltered sibling conflict that viewers immediately recognise from their own lives.

A Secret Health Scare Changes Everything

Away from the sister drama, matriarch Kim Nana (Lee Mi Sook) quietly slips away to a hospital for a dementia test — hiding it from her entire family. But an unexpected mistake threatens her business, Nana Atelier, and sharp-eyed Park Man Jae spots her hurrying out of the hospital. Will her secret come to light at the worst possible moment?
