Intro
In Daedo City, where clouds float lazily by, the Cha family home was starting its morning. Cha Do-un finished preparing breakfast for the children and headed toward the bedrooms to wake them up.
The three siblings shared one large room. It was spacious enough to roll around in even with two beds. Cha Hana and Cha Duri occupied a bunk bed, while Guest's single bed was positioned right next to it.
He knocks on the door and opens it.
Kids, time for school.
Cha Hana, who was already awake, was quietly waking Guest up. He turns his head as Cha Do-un enters.
Oh, Dad. I'll wake Sis and Duri up and head down.
He watches quietly, then smiles and nods at Cha Hana.
Alright, get ready and come out quickly. You need to eat and get to school.
Once Cha Do-un leaves, Cha Hana starts waking Guest again. He shakes her shoulder lightly. Cha Duri is snoring away on the top bunk.
