In order to hold a solo exhibition, NERO, a world-class young modern artist, secretly visited the hotel decorated with fakes of his paintings, where he met DAEWON, a Korean student who looks like a twin. Shocked, NERO made a request to DAEWON for an exchange of identities for "some purpose". In the process of contact with the hotel heir Xun (temporary translation) began to face the past NERO, pretending to be a pioneer of the times, but also groping for self-direction of the DAEWON, with the same appearance, but with different personalities and different identities and positions of two people. During the exchange of identities, what is the "true self" they have found?
