Story Recap
Episode 1
Stella has a plan, and it doesn't include the stranger her family picked out for her. She flatly refuses the arranged marriage and announces that her boyfriend is proposing today — then orders a billion-dollar contract handed over like it's nothing. Margaret, her family's bodyguard, warns that if her father finds out, it will be a disaster.
Then comes the twist: the mysterious CEO everyone whispers about, Richard Castro, is standing right in front of her — the same company she's undercover at as a cleaner. He assumes she's someone else entirely, and Stella realizes exactly who she's just met.
Episode 2
Stella introduces herself as a 23-year-old award-winning cleaner — and Richard takes her at her word. His assistants apparently set him up with a cleaner for a contract marriage, and he doesn't blink: he offers her a deal. Fifty thousand a month, and she pretends to be his wife for two years.
Stella shuts it down fast. She can't marry him; her boyfriend is proposing today. But when Margaret closes in, Stella's confidence cracks, and she asks Richard for a favor: can she hide in his car for a second? He agrees — and the mess only gets deeper.
Episode 3
Richard wants to know who's chasing her, but Stella waves him off — it's better if he stays out of it. Once Margaret is gone, Stella admits the truth: that was her family's bodyguard, and she owes her money she hasn't paid back. She keeps it vague, and Richard doesn't push.
They call it even — he mistook her for a fiancée, she hid in his car. Stella heads off to meet her boyfriend, still believing a proposal is waiting. Instead, James looks right at her and ends it: he's done with her.
Episode 4
James doesn't just dump Stella — he does it with an audience. Barbara steps forward as his boss and his lover, smugly claiming she secured the $100 million contract with Mitchell Oil for him today. Stella corrects her: it was Stella who got him that contract.
Barbara laughs. A lowly cleaner can't even set foot inside the Mitchell Corp building. So Stella says it out loud — she's the heiress to Mitchell Oil Corporation, and she hid it so James wouldn't feel burdened by her family name. James and Barbara don't believe a word. To them, it's a cheesy soap fantasy.
Episode 5
Barbara hands over a check — $1 million, take it and leave James. Stella isn't impressed; that won't cover a few dresses for Fashion Week. She reminds them she could cancel James's contract right now if she wanted to. Barbara sneers that a million is more than Stella could earn in a lifetime.
Stella tries to prove who she is, but her father has cut her off over the refused arranged marriage, and she can't get through. Barbara offers her own phone with a mocking dare. Then she tells Stella she isn't even worthy to touch it.
Episode 6
Barbara keeps piling on the humiliation, but a stranger steps in — Richard Castro. He calls out the real embarrassment: abandoning a longtime girlfriend to hook up with your boss. When asked who he is, he says it doesn't matter. What matters is that Stella is about to become his fiancée, and he'll protect everything that's hers.
James tries to hand over money as a "wedding gift," certain they can't afford a real ceremony. Stella refuses it. She tells James that if this is his final decision, she's walking away — and one day he'll regret leaving her.
