THE SECRET WE VOWED

Married in silence.
Living under the same roof.
Loving where no one can see.

Everyone at Seoul's most prestigious university knows Kim Taehyung.

The cold, intimidating heir of the Kim family. The one who never lets anyone get too close. The one surrounded by six inseparable friends Jin, Suga, RM, J-Hope, Jimin, and Jung Kook.

Everyone knows Kim Taehyung.

But no one knows his biggest secret.

He is already married.

Kim Jisoo is the daughter of another powerful family, elegant, independent, and just as determined to keep her private life away from the public eye.

Their marriage was arranged by their families and kept completely secret. Not even their closest friends know.

And now, they're studying at the same university.

To make them grow closer, their families decide that Taehyung and Jisoo will live together at the Kim family mansion.

Same house.

Same bedroom.

Same family.

But at university, they have to pretend they're nothing more than acquaintances.

Taehyung even has his own private mansion, where he spends time with his friends, parties, and attends events. Whenever he stays there, Jisoo is left behind at the Kim mansion-with a family that already treats her like their own daughter.

They thought keeping their marriage secret would be easy.

Until jealousy appears.

Until feelings begin to change.

Until their friends start noticing the little things.

And until a hidden secret behind their families' decision threatens to expose everything.

Because sometimes the hardest secret to keep...

is the person you secretly love.

They were married before they ever learned how to love each other.
