Overview

• A newly released preview centers on a café confrontation where Sang-yeon reveals a terminal diagnosis and asks Eun-jung to accompany her for assisted dying, prompting Eun-jung to call the request “emotional abuse.”
• The drama stars Kim Go-eun and Park Ji-hyun as Ryu Eun-jung and Cheon Sang-yeon.
• Director Cho Young-min and writer Hye-jin Song present the story as a nearly 30-year portrait of a complicated friendship.
• The production uses the same lead actors across multiple life stages rather than recasting at different ages.
• The plot involves plans for assisted dying in Switzerland, and early coverage has likened the friendship-focused premise to Firefly Lane.
