Story Guide
Episode 1
Layla's blind date is a disaster before the appetizers arrive. The man sneers that she's so short people will think he's "walking around with a hobbit," and that having kids with her would "drag down the gene pool." Layla fires back — good things come in small packages — and walks out, even though she desperately needs a marriage alliance to pay off her student loans.
Outside, a stack of boxes topples onto Madam Marlow. Layla rushes over, checks the woman's injury, and gently applies medicine to the swelling. Grateful, Madam Marlow learns Layla is a 23-year-old Ivy League graduate and immediately pitches her grandson: six feet tall, handsome, thoughtful — and a single father. Then she calls him over. "Your heights are a perfect match," she declares. "Go to city hall and get your marriage license right now."

Episode 2
Cassian balks. Beside him, Layla looks like a high schooler — "Do you want me to get arrested?" Madam Marlow counters that she's 23 and a top graduate, just petite. Cassian insists his heart belongs to his daughter Romy, who needs a mother, not a nanny.
Layla refuses to beg. "Forced love is never sweet," she says — then takes a call about an overdue bill she's scrambling to pay. Cassian softens and admits he's a single father with a four-year-old who plays pranks; being a stepmother won't be easy. Layla promises to try her best — and asks him to help with her student loans. He agrees, joking he'll be broke and she'll have to support them. Madam Marlow shuts down his protests, and within the hour, Layla has married a man she barely knows.

Episode 3
Cassian hands Layla apartment keys and a card for daily necessities. She squints at it — "a supermarket discount card?" It's actually an unlimited black card, but she vows to pay him back once she has a salary. Then she rushes off to report to her new company.
At the translation department, Blair sneers at the "half pint" intern who can't meet the image requirements. Layla doesn't flinch: "My IQ doesn't filter by height." Ordered to fetch a file from the top shelf, she uses a tool instead — and needles Blair right back. Supervisor Cressida lets the squabbling slide, then panics: the CEO, Cassian, is coming to inspect. Layla freezes. Her husband is also named Cassian.
Episode 4
Layla's coworkers laugh off the coincidence — the CEO can't be her husband. Blair jeers that Cressida and Cassian are childhood sweethearts, a match made in heaven. Then the image crackdown begins: Layla is ordered to the back row so she won't "drag down the overall height" or block the CEO's way.
She refuses to shrink. "Height is genetic selection — since when does it determine someone's worth?" The taunts turn physical: a stepped-on shoe, a demand for an apology to Cressida. Layla insists she was tricked. The tension spikes the moment Cassian walks in and sees the commotion — and his secret wife at the center of it.
Episode 5
Cressida scrambles to spin the scene: just workplace etiquette education, plus the intern fails the department's image standards. Then she wonders aloud who hired her. Cassian answers flatly: "I hired her myself. Do you have a problem with that?" He orders Cressida to apologize.
Layla is summoned to his office, where her coworkers assume she's about to be fired. Instead, Cassian tends the wound on her arm himself, gently chiding her for not fighting back when bullied. He asks why she pretended not to know him. Her answer surprises him: she wants their marriage kept secret so she can stand on her own abilities — not on the title of the CEO's wife.
Episode 6
In the office, Layla confirms the truth: the "poor husband" she's supporting is the group's CEO. Cassian can't believe his wealth matters less to her than an internship. When he tells her to take off her coat, she panics — until he clarifies he only wants to treat her arm. "A bristling wildcat" one moment, "a little bunny" the next, he muses. This marriage, he decides, is more interesting than expected.
Outside, Cressida confronts him: she'd wait for him despite his daughter — why marry someone else? Cassian says he's only ever seen her as a friend, and that he'd never marry someone he didn't like. Meanwhile, Layla learns the CEO has quietly raised his child alone for years, the mother's identity a mystery.
Episode 7
Cassian warns that his marriage to Layla stays confidential at the office — don't bring trouble to her work. Cressida presses: is Layla really Romy's mother? No, he admits. It was an accident years ago; he can't even remember the woman's face, and she abandoned Romy. A woman like that doesn't deserve his affection, he says — though Cressida suspects he's truly fallen for Layla and was only pushing her away.
At home, Romy is furious. Madam Marlow told her Daddy found a stepmother, and the little girl vows to personally kick out the "bad woman" stealing her mommy's place. She slips into the company alone, ordering staff not to tell her father — while Cressida fumes about whoever "seduced" Cassian.
Episode 8
Romy runs into Layla and, oddly, feels her heart ache seeing the child hurt. Cressida shoves the girl; Layla demands to know why. Cressida sneers that Layla only got here through luck. Unbothered, Romy decides she likes Layla — "quite pretty and smells so nice" — and declares she'll claim her as her new mommy.
Cressida's mask slips. She insults the child, and when Romy bites her, threatens to teach her a lesson. Layla steps between them. Romy reveals her name and hands over a greeting gift — an emergency asthma inhaler. Upstairs, Cassian learns Romy has vanished and orders a floor-by-floor search. Cressida offers the girl cake as an apology. Romy refuses.
Episode 9
Cressida's "apology" turns vicious. Romy, struggling to breathe, begs for the medicine in her bag. Layla holds her, coaching deep breaths, and demands Cressida hand it over. Cressida refuses — first demanding to know whether Layla was intentionally seducing Cassian in his office.
Layla snaps: "Your target is me. This is just an innocent child. Give her the medicine!" Instead, Cressida lets it drop. Layla digs out her own inhaler — she has asthma too — and helps Romy breathe. Cressida sneers that the two are "like mother and daughter." Then, with the medicine on the floor, Romy gasps for her daddy to save her.
Episode 10
Cassian tracks the security feed: Romy is in the first-floor break room. He races down. Cressida uses the delay as leverage — if Layla wants the girl saved, she must kneel and beg Cressida for mercy, and then they'll send Romy to the hospital.
Layla agrees. "Remember what you said," she warns. Cassian is still at least fifty seconds away. Romy is slipping — an asthma attack tightening its grip while the adults bargain over her life. Layla holds on, refusing to let the child sleep, as the clock runs out and help closes in.
