My Brother Is A Mad Dog

At a top-tier elite high school, students from wealthy families have established their own set of rules, granting the upper echelons supreme power within the school. An Ran, who only wants to behave himself, is relegated to being a punching bag. When he's bullied again, he's unexpectedly rescued by his long-lost twin brother. The two agree to switch identities: the brother, Jin Yansheng, will take An Ran's place and bravely navigate the high school, while An Ran will have to survive in the slums, bearing his brother's reputation as a vicious dog...At a top-tier elite high school, students from wealthy families have established their own set of rules, granting the upper echelons supreme power within the school.
