Her father arranged a marriage for her with a young and rich CEO (Jungkook), just so he doesn't lose his job and money.

She's 20, still going to college. He's 27.

Lately, she have been talking a lot with him. She trusts him. She feels as if he were a friend or an older brother... she doesn't see him as a husband, because she thought he only saw her like a little girl, not as a woman, much less, like his wife.

Big mistake.
