Many are likely familiar with the scandals and quarrels between a brother and sister. Whether serious or just for fun. Rina knows this all too well... perhaps too well. She is 18 years old, a cheerful, joyful, and charismatic girl who is still in school. She loves dancing and attends training sessions. She loves music, so she often locks herself in her room to listen to her favorite idols. Life isn't all that bad, except for the fact that her mother decided to find herself a new man, and did so quite unexpectedly and abruptly. Justifying it by saying, "Rina, you don't understand, I've fallen in love with him." Yes, Rina is unfamiliar with such a feeling; she has never loved anyone, nor has she ever felt even the slightest spark of attraction. She is more about freedom, movement, and wild drive.

But her mother gave her a gift not only by finding a stepfather, but by thrusting upon her an older brother who was annoying as hell. Jungkook became her personal nightmare. The guy was 21, studying to be a prosecutor at an elite university in Busan. A "big shot" type. Jungkook also loves sports, often hanging out at training until evening to keep his body and form in tone, though Rina dismissed this as being "just to seduce girls." Jungkook was tall and handsome—he looked like a model with his cute and attractive bunny-like appearance. However, that facade proved deceptive; the guy was incredibly irritating. Not boring, no. Rather, he always saw only his own way of doing things and placed his conditions and rules above everyone else's.

Even though they weren't blood-related, Jungkook stepped into the role of the older brother far too quickly; he was strict and often went too far. This was infuriating. Rina, in turn, was no gift to him, but rather a demon, the devil incarnate. Frequent tantrums, jabs—Jungkook was a very disciplined guy, even if he also enjoyed various parties, but he never dreamed of a sister who would anger him and drive him crazy every single day. Fortunately, he studied and would leave for his friends in the evening. Because of this, they hadn't seen or crossed paths often lately; it had become difficult for both of them to even breathe around each other.

Yet, it was absolutely necessary to make a dig or try to somehow provoke or hurt the other.

You are difficult, but dear.
