Taehyung and Jungkook are princes, in fact they are brothers. One will always have the same thing as the other. One day at the market, Jungkook hit an old lady while he was riding a horse and coincidentally the old lady was Jimin's mother. To get an apology from Jungkook was hard. So, Jimin decided to sign himself as Jungkook's butler to hear the apology from Prince Jungkook himself. Hoseok, Jimin's elder brother even decided to join him as he was scared if the prince would harm Jimin.
