Episode 7 of "Who is She?" unfolds with a dramatic prelude, where Mr. Park teeters precariously on the brink of losing his footing, the taxi driver looming close behind him. The scene seamlessly transitions to the present, unveiling a younger Mr. Park, now adorned with the moniker Park Joon. Du-ri, her heart lifted with relief, welcomes back her long-missing friend after a period of anxious uncertainty.
Meanwhile, Daniel seizes the moment, capitalizing on the surging popularity of Du-ri and Ha-na by rebooting the new group's concept into a Retro revival, reimagining their debut single with a fresh twist.
Within the confines of their home, Kkeut-soon steps into Mal-soon's family fold, much to Du-ri's lingering apprehension. Amidst unpacking, she stumbles upon a photo album, its pages revealing a cherished snapshot of the twins with their mother—yet, Kkeut-soon's face and their mother's are ominously obscured by scratches.
Elsewhere, Kim Ae-sim's memories resurface, painting a vivid picture of Mal-soon's confrontation, a poignant moment where Mal-soon stood her ground against Ae-sim's crushing dismissal of her dreams.
Later, Kkeut-soon, impersonating Mal-soon with adroitness, confronts Min-seok, Mal-soon's son-in-law. Her voice carries an unwavering authority as she issues him an ultimatum: uncover the identity of the sixty-year-old woman Jin-seok had encountered, or face the consequence of footing the rent.
In the meantime, Park Joon has emerged as a burgeoning ssireum sensation, his ascension illuminated by a nostalgic glimpse into his glory days as a revered youth fighter. The corporation, swayed by the recent publicity stunt showcasing Ha-na and Du-ri's talents, finally breaks its silence and grants them a second chance. At home, Kkeut-soon puzzles over the mystery of the elderly woman in her 60s, realizing with a start that there are no photographs of Ji-seok's father predating his supposed demise, a time when Ji-sook was still an infant.
Park Joon eventually makes his presence known at his own guesthouse, where he decides to take up residence, his arrival preceded by a spirited altercation with Daniel. The subsequent day, Du-ri, observing the youthful inexperience of the female trainees in matters of the heart, regales them with her six decades of wisdom on discerning the right partner. This generous sharing not only enriches her bond with her teammates but also elevates her standing among them.
As Daniel ventures out to finalize a television appearance for Ha-na and Du-ri, a haunting sense of déjà vu envelops him as he detects the eerie presence of his stalker in the men's washroom—a recurring nightmare from his past. Upon his return, accompanied by Joon and Du-ri, a fiery dispute erupts between Daniel and Joon, leaving the episode on a cliffhanger of tension and conflict.
