I Shouldn't Have Slept with Her

"Noona, was sleeping with me... a mistake?"

Jiwan, a returning college student, ends up spending an impulsive night with Seoa, a woman eight years his senior whom he met at a drinking party.

With her neat face and glasses, she seemed like an utterly flawless, straight-laced office worker. But in bed? She was a completely different person.

Completely bewitched, Jiwan is left with only one question: We slept together, so why is she acting like nothing happened?

To make matters worse, it turns out Seoa lives right next door, leading to a series of dangerous nights between the two as they keep running into each other. The more they meet, the deeper Jiwan falls—body and soul. Yet Seoa seems to view him as nothing more than a cute younger guy...

And to top it off, an older rival pursuing Seoa suddenly appears!

It all started with a one-night stand, but now Jiwan wants far more than just one night.

"Noona, can't you start seeing me as a real man now?"

Starting with physical pleasure and capturing the heart, a thrilling and cheeky mature romance between an older woman and a younger man!
