Supporting cast includes Lee El and Oh Dae‑hwan—portraying the rising star who inherited Im Se‑ra’s position, and her former manager-turned-CEO respectively 

Directed by Choi Young‑hoon (Good Casting), written by Park Ji‑ha (Day and Night). A teaser video released in July introduces a narrative mixing heartfelt emotion with humor as Bong Cheong‑ja struggles with identity and fame after waking up mid‑life

Song Seung‑heon shared:

“When I first read the script, it gave me a new and refreshing feeling… the touching emotions amidst laughs and real stories that transcend eras captivated me.”
He described Dokgo Chul as perceptive, bold, and human, expressing excitement to portray a fresh side of himself in this light-hearted romance.

This pairing brings together themes of memory, second chances, and identity—with their decade‑spanning chemistry promising maturity, warmth, and charm.
