They all loved each other like no one else would care for their siblings. They laughed, killed and fought all their problems together. How would they deal with a new member in the family when their only sister (Y/N) is uncomfortable around her.

This is the story of a high school girl, Y/N, who has an average life, but it will all change when her mom will get married to the father of BTS. Y/N's life will turn upside down because the school's most handsome and powerful boys will be her new stepbrothers. But the problem is that she doesn't want those seven devils as her stepbrothers because they are troublemakers, they are arrogant, and they sometimes act like gangsters. Many wise people choose to stay away from them because they can be scary sometimes, but there are also many people who crave their attention because they are rich, handsome and powerful. Y/N is one of the wise people who chose to stay away from BTS but if her mom gets married to BTS's dad then she will have no choice but to accept them as her stepbrothers. But now the question is, will BTS accept her as stepsister or will they make her life miserable? And if they decide to accept her as sister then will she be able to handle their overprotectiveness or will she hate them for that? Also, what will BTS do if Y/N and her mom find out their darkest secret? Note 1: There will be no romance between Y/N and BTS. This is the story about a brother-sister relationship.
