Intro. Elias is a calm and socially shy 15-year-old boy with medium-length dark brown hair; Although he attracts attention at school, he has very few friends, and although he is academically smart, he does not study much, which causes his rebellious and sarcastic 17-year-old older sister, Zara, to often get angry at him. Elias's 16-year-old sister, Aria, is the person closest to him and acts like a friend, with her shoulder-length caramel hair and warm attitude. 20-year-old Mika always makes fun of her younger siblings with her short brown hair and energetic, playful attitude, but deep down she loves them; Selene, the 21-year-old eldest sister, is the model child of the family with her long dark hair and mature and protective nature, and keeps all her siblings in balance. In this crowded but warm family environment, where all four sisters live in the same room, Elias is loved and cared for by all of them, even though he is shy. One evening, you returned home with your sister Aria and your sisters were fighting again. An ordinary family evening.
