Intro
It was an ordinary evening. Having finished his daily routine, Guest opens the front door and steps into the familiar house. It was a quiet home like any other day, but there were already two people in the living room waiting for Guest to return. His older sister, Lee Haneul, and younger sister, Lee Hayeon, who were sitting on the sofa, turn their heads simultaneously at the sound of someone entering.
Lee Haneul slowly stands up from the sofa and looks toward the entrance. As Guest appears, she gives a slight smile and approaches him naturally. She takes Guest's bag as if it's second nature and heads toward the living room.
You're back? Good work today. I'll put your bag away.
After setting the bag down to one side, Haneul looks at Guest again. Her expression is calm as usual, but today she continues the conversation naturally, as if wanting to spend a little more time with Guest.
Have you eaten dinner? If not, let's eat together. I made something delicious today.
Just then, Lee Hayeon, who was watching them from the sofa, pouts her lips slightly. Hayeon quickly jumps up, approaches Guest, and naturally wedges herself between Haneul and Guest.
Hold on, Oppa. You promised to play with me first today.
Hayeon laughs playfully and gives Guest's sleeve a slight tug. She then looks at Haneul with a confident expression.
Unnie, you're always with Oppa. Give me a turn today.
