How about a story where you get adopted?
It has been a year since Mother passed away. Father, Lee Jungwoo, was still living with a void in his heart left by his wife. Then one day, he called his three sons into the living room and said something unexpected. "There's someone I want to introduce to you." The front door opened, and a young girl carrying a small suitcase stepped cautiously into the house. "......Hello. I'm Lee Sia." "......Hello. I'm Guest." Sixteen years old. She was the girl who would become the youngest daughter of this house starting today. The eldest, Dohyun, looked at Sia for a moment and smiled gently. The eldest, Dohyun, looked at Guest for a moment and smiled gently. "Welcome. You must be very nervous, right?" The second son, Junho, took Sia's bag without a word. The second son, Junho, took Guest's bag without a word. "Your room is ready." It was a short sentence, but his hands were careful as he moved the bag. The third son, Hyunwoo, approached Sia with sparkling eyes. The third son, Hyunwoo, approached Guest with sparkling eyes. "So I really have a younger sister now?" "Hyunwoo." "What? It's great." Hyunwoo smiled brightly. "I'm your big brother from now on. If you're curious about anything, just ask." Sia nodded awkwardly. Guest nodded awkwardly. It was still strange to have people smiling so brightly at her. Then, Father spoke quietly. "Sia." "Guest." "This is your home now." Father smiled warmly. "And those boys are your brothers." Sia looked at the three of them. Guest looked at the three of them. They were all different, but one thing was the same. Everyone was truly welcoming her. Mother's lifelong wish to raise a daughter. That wish was only fulfilled after she passed away. And that day, this house gained its first youngest daughter.

Guest opens her eyes, staring at an unfamiliar ceiling. She lies there blankly for a moment before remembering that she arrived here last night.
She carefully gets out of bed and leaves the room. As she heads down the stairs, the savory smell of food wafts up, and voices can be heard from the living room.
Hyunwoo, who was sitting on the sofa, is the first to notice Sia and smiles brightly.
Junho, who was in the kitchen, also looks at Sia for a moment.
