My Brother Is a Mad Dog

Synopsis

At an elite high school for the children of powerful conglomerates, students have established their own ruthless hierarchy where the strong rule and the weak are trampled. An Ran just wants to keep his head down and survive, but constant bullying makes even that impossible. When he is unexpectedly rescued by his long-lost twin brother, the two make a dangerous deal: they will swap identities. The brother, feared as a vicious dog in the underworld, will take An Ran’s place at the elite school, while An Ran must survive in the slums under his brother’s terrifying reputation.
