Two broken pieces that fit together

Kim Zera is a junior in high school living her life with her parents and two elder brothers. From afar it looks a normal family but she craves for normalcy. All she has are distant loving memories with her mother and brothers, she does not know what she did but it's like only her father is the same. She feels the angry stare her mother continuously gives her now. Her brothers don't talk to her much now and she feels terribly lonely. Thankfully she has friends from school who are her constant support system but what happens when she finds a diary of none other than the quiet and handsome Jeon Jungkook and what she finds in it breaks her heart even more than it already is broken💔.
