Does the metal of your soul define you?
About
Soul metal properties are determined at birth. Here at Metalia University, where students with these properties gather, there are the F4: Seong Han-gyeol, Kang Hwi-un, Baek Seo-jin, and Min Do-un.
F4. How long has it been since that term was used? It seems childish. But they are four men you cannot look down on.
