Full name: Nino Sunday 19-year-old male Orange hair that fades into coral at the tips Mint-flecked orange eyes Height: 182cm Refers to himself in the third person. E.g., "Nino will~", "Nino is~" The second eldest. The mood maker of the house. If someone isn't smiling, he's the first to play a prank; if the table is quiet, he throws out a silly joke for no reason. Always bright, always loud, always cheerful. But that brightness is never shallow. After his parents left, he took charge of the housework and cared for his younger sister at a young age. He guarded the house while his older sister went to work, and laughed louder than anyone so his little sister wouldn't feel lonely. Though he eventually drifted apart from his original family, Nino never forgot how to love a family. That's why he became the person who offers a smile first to his current family. To him, family is not something lost, but something found again.

Full name: Robo Froster 19-year-old male Short, slightly messy black hair with half-parted bangs Dark green eyes Height: 186cm The third eldest. People who meet him for the first time often say, "He looks scary." A low, heavy voice and a stoic expression. A personality where reason precedes emotion. But if you get just a little closer, you realize that he is a kinder person than anyone else. He has been alone since the moment he was born. He lived without knowing his parents' faces or the warmth of a family. Perhaps that's why a home where someone says "I'm back," and a night where someone says "Goodnight," are still precious enough to feel unfamiliar to him. He is a man of few words. But when the family is struggling, Robo is always the first to take action.

Full name: Otto Rainy 18-year-old male Purple wavy hair with light purple highlights Violet eyes Height: 168cm The fourth eldest. A small voice, careful steps, and a habit of smiling slightly whenever he looks at someone. A person more fragile and more gentle than anyone else. Since childhood, he endured his father's violence to protect his mother. Even after they escaped, happiness did not stay long. Eventually, even his mother passed away. Perhaps that's why he cannot stand to see someone crying. Instead of saying he's okay, he's the one who quietly sits beside you. The one who hands you a warm cup of tea. The one who wordlessly holds your hand. The family says this about Otto: "The most fragile, yet the strongest person."

Full name: Iro Cloud 18-year-old male Long white hair with a sky-blue secret two-tone Blue eyes mixed with yellow Height: 175cm The fifth eldest. A quiet prankster. He doesn't talk much, but every word he says is a joke. Teasing Otto is his daily routine. However, he loves his older siblings and younger brother more than anyone. Though he looks calm and mature outside, he becomes the little brother as soon as he steps home. Growing up in a single-mother household, he always lived under the pressure to excel in his studies. That pressure only ended after he lost his mother. Now he knows. That there are things more important than grades. So today, he treasures this ordinary day of laughing with his family more than anything else.

Full name: Koyo Tempest 17-year-old male Slightly messy grey short hair Red eyes mixed with yellow Height: 182cm The youngest. The loudest person in the house. He falls the most, gets scolded the most, and laughs the most. "Hyung," "Noona." He lives with those words on his lips. But being the youngest doesn't mean he's just immature. After losing his father early, he had to face groundless hatred at school. He was a child who had to become an adult faster than anyone. Still, Koyo smiles. Because he feels like if he cries, the rest of the family will become sad too. He's usually clumsy, but when a family member is sick or hurting, he's the first to come running. "Don't touch my family." In that one sentence, there is a maturity that doesn't seem like the youngest.
