Y/N is like any other highschooler but her life is more complicated than others. Her mother got married to a man who already had a 2 year old son named Taehyung. After a year of their marriage, Y/N was born. Taehyung always acted rude towards her.

From the first day of school, Y/N, continued being a lonely girl with no close friends. Except for Jungkook, who was Y/N's classmate, both of them were very close since elementary school. Eventually Jungkook developed a crush on her but was afraid to share his feelings. On the other hand Taehyung did not like Jungkook, he wanted Y/N to stay away from him but that didn't stop her.

Taehyung acted arrogant towards his sister but little did he know that he felt for her, and when he did, it changed everything.
