A Long-Awaited Memory Return and a Quiet Bench Confession
After wandering in confusion following his head injury, Ji-woo finally snaps out of the fog and remembers who he is. More importantly, he remembers Jin-hee. Instead of letting misunderstandings fester, he reaches out to her, clearing away the lingering uncertainty that kept them apart throughout his recovery.
Sitting side by side on a quiet neighborhood bench, the two drop their guard and share the emotional scars they carried for years. Ji-woo opens up about the bitter loneliness of his high school years, particularly the painful day his birth mother promised to meet him but never showed up. Hearing him articulate that childhood abandonment brings Jin-hee visible relief and empathy. By acknowledging their shared vulnerabilities, they cement their bond and agree to move forward as an official couple.
Seri's Furious Warning and Painful Past Wounds
The romantic atmosphere does not last long once Ji-woo walks Jin-hee back to her front gate. Jin-hee's mother, Seri, steps out into the alleyway and instantly shuts down the moment with icy hostility. She orders Ji-woo to leave her daughter alone, completely unmoved by the news that his memory has returned.
Inside the house, Seri spells out why she refuses to give an inch. Her hostility is not random parenting stubbornness; it stems from deep trauma tied to wealthy elites and a long-standing grievance with Do-hee. Years earlier, Do-hee's schemes derailed Jin-hee's education, preventing her from attending regular high school. Seri warns Jin-hee that Ji-woo comes attached to predatory parents who would rather embrace a criminal heiress than welcome an outsider like her daughter into their home.
Confrontation in the Storage Room: Unmasking the Deception
Rather than alerting his parents about his recovered memory, Ji-woo summons Do-hee to the book storage warehouse. Picking that specific spot is a sharp tactical move. It is the exact location where Do-hee once locked Jin-hee away, making it the setting where her web of control began cracking.
Surrounded by stacks of books, Ji-woo lays out every calculated transgression Do-hee committed. He calls out the stolen artwork she passed off as her own, the hit-and-run accident that triggered his trauma, and her scheme to drag an amnesiac man into a sham wedding before shipping him off to London. Do-hee attempts to deflect, but Ji-woo shuts down any lingering illusion of romance between them, drawing an irreversible boundary.
The Stolen Seal and the Shocking Marriage Certificate Twist
Just when it feels like Ji-woo has taken back the upper hand, Do-hee drops a vicious legal bomb right before the closing credits. While Ji-woo was distracted, Do-hee stole his national identification card and personal seal, rushing an official marriage registration through administrative channels without his awareness.
With an active marriage certificate now printed and presented directly to his parents, Do-hee flips the entire legal playing field. On paper, she is his lawful spouse, which suddenly frames Jin-hee as an extramarital homewrecker in the eyes of society. Ji-woo pulls Jin-hee into an embrace outside her door, burdened by the looming storm. While a nullification lawsuit remains an option down the road, undoing official registry records takes months of litigation. In the meantime, Do-hee holds legal authority to turn Jin-hee's daily life into a living nightmare.

Frequently asked questions
Can Ji-woo cancel the fraudulent marriage registration that Do-hee filed?
Legally, because Do-hee used Ji-woo's identification card and official seal without his consent, he has grounds to pursue a marriage nullification lawsuit. However, completing a legal cancellation takes time through the family court system. Until the registry entry gets cleared, Do-hee holds legal standing as his spouse on paper, giving her immediate leverage to harass Jin-hee.
Why is Jin-hee's mother Seri so determined to keep Ji-woo away?
Seri experienced immense pain dealing with chaebol families in her past, and she knows how ruthlessly Do-hee has targeted Jin-hee before, including sabotaging Jin-hee's high school education. Knowing Ji-woo's family is willing to cover up crimes and back Do-hee, Seri fears her daughter will suffer the same misery she endured.
Did Ji-woo's parents know about Do-hee's secret marriage filing?
Ji-woo's parents previously showed a willingness to sweep Do-hee's hit-and-run under the rug and push Ji-woo off to London to protect their family standing. While their direct foreknowledge of the specific paper filing was kept ambiguous, the sudden submission of the certificate to their room suggests Do-hee moved quickly to lock in their tacit approval.
