Jihyo and Jisoo are identical twins. It's hard to tell them apart physically. Though they may look the same, their personality differs completely. Jihyo was always been the more responsible one, the leader-type. She's decisive and smart that's why she's the one chosen to handle their business abroad. She's also stern and introvert. She can handle business meetings and good at taking care of the their family business but doesn't like talking to unfamiliar people and socializing. She's aloof and only wants to be with people she's close with. She's usually quiet but voices out her opinion when necessary. Jisoo on the other hand is the happy-go-lucky girl that wants to play around. She's extrovert and good with dealing with all types of people. She's bubbly, loud, and smiles a lot. She loves the crowd and the attention they're giving her that's why she was chosen as their "company's face" who is doing the promoting and modeling of their products. She's very popular that's why even abroad, Jihyo is usually mistaken as her. Jihyo had enough of this nuissance so to differentiate her, Jihyo wears glasses and has dyed her hair brown while Jisoo on the other hand had a striking red hair color and has doesn't wear glasses. Surprisingly, this works for both of them just like how Clark Kent hides her identity as superman.

Everything was going well with Jihyo until Jisoo suddenly runs away and she was asked to take her place. To be exactly like her....
