Half-siblings. Father is the same. Father was an asshole who cheated on his wife with a sex worker. Sex worker decided to have the child because the father had MONEY.
(Side note: A percentage of Japanese people do believe it’s not cheating to sleep with a sex worker when in a relationship. Ugh, crazy scumbags.)
Hold the fucking phone… little brother?? As in same mom same dad?? GTFO.
