Oops! I Ended Up with My Sister's Man Full Episode
001
A Notts-Devins alliance wedding is interrupted when the Notts' flight hits heavy turbulence; with the grooms delayed, the families rush the ceremony with only Elly and Katie present. Elly forgoes a wedding dress, they exchange rings, and Elly slips the family's heirloom onto Katie, provoking shocked gossip. After quick congratulations Katie is sent to Villa 3 to rest. At the villa arrivals shiver; one guest warns, "Katie is just a young lady. Control your temper. Don't pick on her." The episode closes with Katie lodged but under scrutiny, her acceptance into the Notts' household unresolved.
002
During their stormy wedding night the power goes out and Eliza—known for being ruthless—stands in her husband's room. He panics at her youth, admitting it's been ten years since he last saw that little girl and that marrying someone so young makes him feel like a monster. Eliza refuses to leave, presses him to conceive and threatens divorce and to pick a new husband if he fails. He answers, "Try me, and you'll find out if I can." Morning's ultimatum hangs: pregnancy or divorce.
003
On a morning governed by the Nott family's rule granting newlyweds an extra hour in bed, Katie wakes to find Cedric in her room after an implied night together. She lashes out—"You jerk!"—accusing him of using and discarding her while he insists it's a mistake. The confrontation escalates as a phone call identifies Eliza and Cedric agrees they should meet. Others shout for Edward and hurry toward the house. Cedric tells someone, "Take care of Katie. We'll be there soon," leaving Katie with his denial and the imminent arrival unresolved.
004
Elly arrives at the Notts' after a storm and is hurried to get dressed because Eliza and Edward will be here soon. Kat explains she went to the wrong villa during a blackout, mistook Cedric for Edward and held onto him—prompting someone to ask, "Did Cedric force you?"—and they realize rain and leaves hid the villa numbers. Kat says she wants to stay with the Notts. Cedric is called "intense," and, facing the accidental mix-up, the group proposes swapping partners, leaving that plan unresolved as Eliza and Edward approach.
005
A power-broker proposes swapping partners because the marriage license isn't official, saying their influence will prevent interference and protect reputations. When a young woman objects that he decided without asking, she's reminded of last night's passion and reluctantly agrees. The deal settles with Cedric instructed to take care of Kat while the elder handles business. At home, someone awkwardly calls Cedric 'honey' and he resists; then he's ordered to pack — they leave for Delmar in two hours. The episode ends with Cedric stepping into an imposed domestic role as the departure looms.
006
Cedric picks up Katie and immediately imposes rules in his car: no eating, punctuality, and strict public behavior to protect the Notts' image. He presents prenup-style terms she must accept as his partner—attend official events, curb her freedom, and maintain a regular marital relationship for the family alliance. Katie bristles, compares him to Elly, and accepts a packed meal despite protests. The confrontation peaks when Cedric mandates intimacy “twice a week.” Noting the car’s soundproofing, they decide to test the rule now, leaving Katie’s response unresolved.
007
Back from abroad, Edward is mobbed by admirers and rushed into work. A woman who apologizes for injuring his knee appears in his office, saying she "lost control" and offering to help — then proposes squeezing sex into his tight schedule. They attempt a quick encounter, but an emergency online meeting interrupts. He insists she focus on work and leaves; she says it's easier to get pregnant this way and that "my secretary will plan our married life." He protests he hasn't proven himself; the meeting pulls him away, leaving their plan unresolved.
008
After sex, two hours and seven minutes later, Elly is too drained while Cedric urges a shower, mocks their shifting positions, and teases his stamina. Playful banter curdles to argument: he offers to carry her and orders her to get dressed; she snaps, "Cedric, I hate you," then showers. He tries to clothe her; she refuses and demands the white nightgown from her suitcase. He says he'll wait outside the car and that he has things to do. Exhausted, she admits she fell asleep earlier, says she missed him, and asks for a break, leaving the rift unresolved.
009
At a late-night work stop, a man who’s been "working all night again" returns a lamp and brings a cake to a woman, triggering a tense apology scene. She warns him not to wear himself out, accuses him of staging the bakery visit, and demands he admit he wants to apologize. Pressed, Cedric is told to sit while she finishes work. After a pause she says, "I forgive you. I accept your apology." Later teasing—"Chubby girl"—prompts a rebuttal, and someone asks, "Is she upset again?", leaving the truce fragile.
010
Morning in a shared bedroom: Cedric nitpicks Katie's sleeping posture and weight, prompting a flinch when he calls her chubby. She resists; a brief scuffle and a BMI check reveal she's underweight (BMI 17), not chubby. Katie snaps that she isn't Elly, and Cedric decides to be patient on their second day of marriage, promising to teach house rules. Later, Edward calls Elly's phone; the woman answering—who insists "I'm your sister-in-law"—says she will tell Elly to call back. The episode ends with Elly absent and her phone in someone else's hands, unresolved.
