If you had three months left to live, what would you do?
Kim Hyoyeon isn't dying, but might as well be when stuck in an arranged marriage with a man she hasn't even met before. The only way to cope with this is to complete a bucket list she had created when she was young and try and find independence before she is married.
Although, she never excepts to meet a shy man by the name of Lee Hyukjae while doing so. Nor does she expect to fall in love with him. But that is exactly what happens.
What happens next, however, will be her choice.
