What’s Happening in Episode 5?
The emotional core of the drama has quietly shifted to Kim Nana (Lee Mi Sook) — the sharp, self-made fashion house founder who is now fighting a battle her family doesn’t know about. After noticing worrying signs like frequent forgetfulness and losing her bearings mid-crosswalk, Nana suspects she has dementia.
In a painfully quiet act of pride, she asks only one person to keep her secret — Cha Yoo Gyeom (Kim Tae Young), her granddaughter Ha Dam’s boyfriend, who happened to help her the day she got lost. It’s a strange, tender secret between two unlikely confidants — and it’s already starting to fracture relationships.
Nana’s Plan: Pass the Torch Before It’s Too Late
Episode 5’s most gripping development is Nana’s decision to begin putting her affairs in order. With her symptoms worsening, she sets her sights on her eldest granddaughter Song Ha Ran (Lee Sung Kyung) — a woman emotionally shut down like a long winter — as the heir to Nana Atelier, the fashion house she built from nothing.
She calls Ha Ran in under the pretense of management lessons, but Ha Ran is sharp enough to sense something’s off. Why the sudden urgency? Why now?
Meanwhile, Yoo Gyeom quietly watches over Nana behind Ha Dam’s back — and Ha Dam is beginning to notice. Tension is building fast.
On a warmer note, Nana’s visit to Park Man Jae (Kang Seok Woo) at his café brings a rare moment of joy — he presents her with a gift he couldn’t give her 55 years ago, and a trip to Chuncheon filled with shared memories is now on the table.
The drama beautifully captures the emotional world of Korean television drama — weaving romance, family secrets, and generational bonds into something deeply human.
