A Happy Trip That Turned Into a Nightmare
Everything looked so peaceful at first. Kim Nana — quietly preparing for retirement and battling memory lapses she feared were signs of dementia — embarked on a nostalgic trip to Chuncheon with longtime companion Park Man Jae. The stills show the two of them strolling through familiar streets, teasing each other, and sharing warm memories. For a brief moment, it felt like the drama was giving her a respite from the weight she’s been carrying.
Then Man Jae stepped away briefly — and came back to nothing. Kim Nana was gone. No phone. No coat. Just absence. The kind of disappearance that hits differently when you already know someone is struggling with their memory.
The Family Is Starting to Notice
The episode builds dread carefully. Ha Young had already spotted Nana crying alone on the street in a previous scene, and when she saw her grandmother return home late at night wearing mismatched shoes, her concern crossed into alarm. The people around Kim Nana are beginning to piece things together even as Nana herself tries to hold the secret close — rushing away from a hospital appointment the moment a work crisis called, as if still refusing to accept what might be happening to her.
Lee Mi Sook is one of South Korea’s most respected and decorated veteran actresses, and her nuanced, layered portrayal of Kim Nana’s quiet struggle has been the emotional centrepiece of this drama from the start.
