Shiraishi Sara lives by one motto: Honesty is the best policy—though her ex might argue that's what got her dumped. Turns out, blurting out that she'd rather date a rich guy for fancy dinners than an emotionally unavailable man wasn't the winning strategy. Heartbroken and furious, she dials up her lawyer friend Yuri to rant—only to find herself talking to someone else entirely.

Enter Fujin Isamu, an aloof IT CEO with the charisma of a high-tech vending machine and the voice of a smooth jazz record. Isamu, who's pretending to be a humble landlord named "Daichi," listens in amused silence as Sara's unfiltered rants range from her love for luxury to her dramatic breakups. Despite his stoic exterior, her boldness stirs something he hasn't felt in years: Laughter.

But Isamu's family has other plans. Convinced their son is more likely to marry kabuki than a woman, they push him into an engagement with a high-society lady. He declines. His tells them about Sara being his girlfriend! So, what does a stoic CEO do next? He calls Sara, the woman who would probably marry a frog if it came with a platinum credit card, to pose as his girlfriend.
Cue fake dates, meddling relatives, and one hilariously awkward hot spring trip. As they fake their way through Isamu's family's expectations, Sara and Isamu realize that love, like sushi, is best served fresh and unexpected—especially when it's wrapped in a whole lot of complications.

But when Sara discovers that Daichi's humble landlord persona hides an empire of wealth, she's forced to question everything, including her love of fine dining. After all, as the Japanese saying goes, "Even monkeys fall from trees," and sometimes, love finds you when you least expect it-or when you accidentally call the wrong number.

Get ready for a rollercoaster of laughs, luxury, and love that might just make you believe in fate...or at least in the wrong number.
