The heir to the Beomho Group, Kwon Yeol, has one boundary that no one dares to cross.
It is Yoon Heejo, the younger sister of his late friend, who was left all alone after her brother Heejae passed away.
Determined to take responsibility for his friend, Kwon Yeol promises to become her family in his place.
But one day, Heejo makes an unexpected request.
“Can I ask you a favor, oppa?”
She had never asked for anything before, which piques his curiosity.
“Please… sleep with me. Just once.”
His surprise lasts only a moment.
If it’s Yoon Heejo, Kwon Yeol would grant her anything—
Even if it’s her desperate attempt to leave his side.
“Then let’s get married. Just for one year.”
What he doesn’t realize is that the little girl he once knew and the woman Yoon Heejo has become are completely different.
And that he will be consumed by her far more deeply than he ever imagined.
After becoming husband and wife,
even though their relationship is built on a lie, Heejo finds happiness.
But dreams are meant to end.
Having held something she believed she could never have, Heejo decides to say goodbye to Kwon Yeol—
Not as her husband, but as her brother’s friend.
