Seven years into their marriage, business partners Mi-young and Won-ho maintain only the illusion of a happy couple. When Mi-young secretly agrees to appear on a variety show behind Won-ho's back to save their struggling company, unhealed wounds resurface, leading her to make a fateful choice on a bridge over the Han River.

Following the incident at the Hangang Bridge, Mi-young demands a divorce, but Won-ho refuses to accept reality. When Cheon Man-joo, a young celebrity, asks them to design her dress, the two agree to put the divorce on hold. However, things take a wild turn when Man-joo collapses at her party.

Won Ho is thrown into shock after hearing Mi Young call him a murderer. He is introduced to an attorney through Mr. Kwon and begins to prepare for the divorce. Meanwhile, Mi Young's first love, Calvin, reappears and subtly makes his feelings for her known. Burning with ambition, Mi Young puts everything into making the collaborative J&WHITE trunk show a success, but right before the curtains are raised, something unexpected happens, putting the show in jeopardy. Will the show end successfully?

Having pulled off a successful trunk show, Mi Young tries to thank Won Ho, but he doesn't answer. To make matters worse, a misunderstanding involving Won Ho and Hee Ju hurts her once again. Won Ho flies into a rage when Mi Young starts collaborating on another project with Calvin without consulting him, while Mi Young is left in shock after uncovering Calvin's hidden past. Amidst all this, a critical photo left by Hee Ju only drives a deeper wedge between Mi Young and Won Ho.

After growing closer to Calvin and hearing Won Ho's intention not to divorce her, Mi Young's will toward the divorce takes a turn. The past she once believed in is flipped on its head when she first hears the truth about Calvin's divorce. What's more, after a conversation with Mr. Kwon, whom she believed was the reason for her and Won Ho's tarnished relationship, she finds out crucial information about the past that changes everything. Now she must face the shocking truth.

After learning the truth about what happened three years earlier, Won Ho wants to leave the past in the past, but Mi Young's attitude toward him does a complete 180. What were harsh words become sweet comments and kind gestures, making Won Ho more uncomfortable than before. Later, Hee Ju gets into a freak accident during a shoot on a cliff, and Won Ho gets kidnapped by mysterious assailants. Will either of them return safely?

After being discharged from the hospital, Hee Ju waits for Won Ho, only to be told by Mr. Kang that she won't be able to see him anymore. Chi Hyun tries to use Won Ho's affair to gain leverage in the lawsuit, but Hee Ju, bitter that Won Ho is ignoring her calls, hands the photo in question over to someone. Soon, the family court investigation begins, and Mi Young and Won Ho slowly open up about the feelings they had put off. Or at least, that's what Won Ho thought.

After the family court investigation, Won Ho claims his innocence, but Mi Young insists the cause of her miscarriage was due to medicine he gave her three years ago. As he pursues the truth behind the medication, an unexpected person emerges as a suspect, and Won Ho uncovers a crucial clue that leads him to suspect someone is pulling the strings behind it all. Who is the mysterious person that may be the cause of so much tragedy?

Kyung Tae is revealed to be connected to the oriental medicine that caused Mi Young's miscarriage. Following her own suspicions, Ah Ri does some digging of her own and finds a decisive piece of evidence in Kyung Tae's drawer. Meanwhile, while trying to find out why Won Ho missed the family court evaluation, she stumbles upon the pain he's been carrying all by himself. As the two get a chance to reexamine each other's pain and sincerity, are the doors to a rekindled romance slowly opening?

Mi Young and Won Ho confirm their feelings for each other and start anew, but both struggle to bring up dropping the divorce lawsuit. Meanwhile, Ah Ri discovers damning evidence inside Kyung Tae's drawer as Won Ho plans a surprise proposal for Mi Young.

Won-ho's snap decision leaves Mi-young reeling as she aches with a longing for him she doesn't want to admit.

After seven years of marriage and tumultuous divorce proceedings, Mi Young and Won Ho share their last sincere sentiments for each other at the courthouse. Although an amicable break, both sides seem sullen, but life must go on. One year later, J&WHITE is up and running again and as busy as ever. With life back to its normal hustle and bustle, will everyone get the happy ending that they hope for?
