Jeong Ji-an

In 21st-century Korea under a constitutional monarchy, a chaebol heiress with everything but status tries to take control of her future after crossing paths with a lonely prince with nothing but his title. Together, bound by a contract marriage, they begin a class-defying romance to rewrite destiny.

After life's ups and downs, a loving couple separated by death reunites in heaven — only to discover he's in his thirties while she's in her eighties.
