Poni and Mini are identical twins. They’re the same height, the same weight, they get the same grades in high school, and even play the same position on the basketball team. All of which tends to make people forget that they are individuals. For Poni, the elder twin, the biggest challenge is to make people realize how different they are. But even Ping, Poni’s secret admirer, is unable to tell the girls apart, sending gifts to Mini’s classroom by accident. And the girls’ new basketball coach treats them as a duo, sending them out on the court as a pair. When Mini’s boyfriend, Yogurt (who can tell them apart), can’t handle Mini, he comes to Poni to ask her advice. Poni can’t understand why people think twins are so mysterious. In her opinion, twins are just two people who happen to look alike. But then why is it that Yogurt can tell them apart, when Ping can’t? This makes her think Ping cannot actually like her for who she is, but sees only the appearance. This one instance of mistaken identity leads to two identity crises, and two very complicated lives. And one kept secret leads to two sisters being torn apart.
