Memory Recovery and the Confrontation at Home
The latest hour of Certificate of Family Relations delivers pure emotional catharsis before dropping an absolute bombshell on everyone involved. Things kick off on a sweet note when Ji-ni sits at the piano. Hearing those familiar melodies breaks through Ji-hoo's fog, completely restoring the memories he lost from that brutal crash. He shares a quiet, heartfelt moment with Ji-ni on the neighborhood steps, promising to call her later that evening and making it clear they belong together.

That romantic high doesn't last long, though. The second Ji-hoo walks through his front door, he walks right into his parents wrapping up wedding arrangements behind his back. Without missing a beat, he shuts the entire conversation down. He tells his parents that his mind is totally clear now and that he won't marry Do-hee under any circumstances. Even wilder, he spells out the awful truth about his accident: Do-hee was actually aiming her car at Ji-ni, and he got hit shielding the woman he loves. You'd think that revelation would stop his parents cold, but his dad refuses to budge. Check out the wardrobe choices from this tense home encounter over in our Certificate of Family Relations Episode 67 Outfits Guide.
Do-hee's Stolen Identity Scheme and Unhinged Claim
Just when Ji-hoo thinks he's laid all his cards on the table, an official certificate gets handed to him. Do-hee went behind his back, swiped his personal identification, and submitted an official marriage registration. It's fraud plain and simple, yet Ji-hoo's father, Lim Jung-bin, tries to defend the document. Jung-bin is so obsessed with family pride and Do-hee's chaebol-level family wealth that he tells his son the paperwork is set in stone.

When Ji-hoo asks his dad if he's basically handing him over to someone who tried to kill him, Jung-bin responds by slapping him across the face. Ji-hoo doesn't back down for a second. He calls out his mother's shallow vanity and his father's hollow reputation before storming straight over to Do-hee's place. The energy in that apartment is completely unhinged. Ji-hoo flings a sofa cushion in sheer disbelief, but Do-hee isn't shaken at all. She openly admits her toxic obsession, making it crystal clear that her entire endgame revolves around tearing Ji-ni down. Sharp corporate family melodrama fans following our Family Register Episode 66 Outfits Style Guide will recognize just how rapidly this domestic friction escalated.
Legal Vulnerabilities and the Annulment Path
Do-hee thinks she pulled off a checkmate by waving the marriage certificate around, but she actually handed Ji-hoo the exact weapon he needs to destroy her. Under standard civil code, a marriage filed without genuine mutual intent or valid personal consent is completely voidable through an annulment lawsuit.

Her move is identity theft and document forgery, which drags criminal liability right into her lap alongside potential charges regarding the vehicle crash. Do-hee acts smug, thinking she can brand Ji-ni an outsider, but her legal standing is built on thin ice. Instead of securing her position as a legitimate spouse, she basically signed a paper trail that points straight to her own misconduct.

When Do-hee dials Ji-ni directly to rub the certificate in her face and launch verbal insults, she expects Ji-ni to crumble in shame. That petty power trip backfires big time. For viewers who enjoy high-stakes family tension similar to what we tracked in the Four Hands Episode 8 Recap, watching Do-hee's overconfidence set up her inevitable downfall is insanely satisfying.
Ji-ni's Decision and the In-Law House Showdown
The closing stretch of episode 67 really brings the drama to a boil. Ji-hoo rushes over to Ji-ni and drops to his knees in front of her mother, Roh Young-joo. He begs for their trust, promising that he'll file an annulment lawsuit, clean up the fake paperwork, and make sure Ji-ni's name remains completely spotless. For a guy who spent years just going through the motions under his overbearing family, this is the very first time he's fighting for his own future.
Young-joo remains cautious because she wants to shield her daughter from any more public scandal. Then Ji-hoo's mother barges into the room, furious that her son is kneeling before another family. The generational clash is brutal: Ji-hoo's mother sees Ji-ni as a problem dragging her golden boy down, while Ji-hoo views Ji-ni as the only person who gave him a reason to live.
Ji-ni, on the other hand, is done playing defense. She wipes away her tears, gathers her strength in front of the mirror, and makes a shocking choice. Rather than running away or waiting on the sidelines while the families squabble, she decides to move right into Ji-hoo's family residence. Stepping straight into the lion's den gives her front-row access to challenge Do-hee's antics and stare down Ji-hoo's parents every single day. That bold move sets up an absolute war inside the household heading into the next chapter.

Ji-hoo regained his full memories after listening to Ji-ni play the piano, which brought back his memories of their bond and what actually happened during the car crash.
