Secretly Alone with My Brother’s Friend

She’s 22 years old. Her occupation? Selling in-game items, basically unemployed. Her hobby? Reading, especially high-class steamy romance novels and webtoons.

Yeonseo, a homebody who somehow never has enough time despite spending all 24 hours a day at home, finds herself face-to-face with Hyun Yugeon, her older brother’s friend who suddenly left to study abroad several years ago.

“I’ve had some things come up, so I’ll be staying at our house for a while.”

Thus begins a strange cohabitation with her brother’s friend, all because of a favor from her sworn-enemy of a brother.

She thought that as long as she stayed cooped up in her room, they’d never have to cross paths.

But somehow, she keeps running into him.

“I’m not interested in little girls.”

“You don’t need to worry about me either, Oppa. The little girl who used to chase after you because she liked you is long gone.”

But the man who used to tease her by calling her things like shorty, little girl, and brat whenever he got the chance…

“You’re in big trouble now. You’ve just missed every chance to meet all the handsome young guys your age.”

Somewhere along the way, he starts crossing the line.

“But there’s one thing I’m much more confident about than those fresh-faced young punks.”

“O-Oppa…”

“Do you really think they could be as handsome as me? Or have as much stamina? Or measure up to me?”

And he does it in a way that is both dangerous…

and tantalizing.
