Identical twins, Sandie and Darie, had been separated from the start of their parent’s divorce and grew apart as different as any twins can be.

Darie was the studious, sophisticated type who grew up with her mother, the heiress of the RanKim wealth and the owner of the Kim Industries. She has been brought up as the epitome of class and elegance and only had one goal in mind. To graduate high school with top honors and get into the best college.

Sandie was the indomitable, imperious type who grew up with her father, one of the triad leaders of the Mark Of The Seven Sign Society, a highly infamous organization in the country. She has been brought up as spoiled and as pampered as much as her father can spoil and pamper her but she only had one goal in mind. To graduate high school and be a member of his father’s circle.

Their lives went into uproar as they were given the ultimate test of their patience when their dead grandfather played a joke on them on his will so they could receive the inheritance that each has been “dying for”.

Live as the other for a month.

It was insane! They would have to be pretend to be each other for a month? In secret? It was ridiculous! Downright crazy!!

But the lure of that inheritance made the twins agree. Darie would have to be Sandie and Sandie would have to be Darie.

Teemed with highschool rules that they had never encountered before, they tried to sail through the condition perfectly and flawlessly.

But things may not be as easy as they thought it should be.
