Intro
For Guest, who had just returned from abroad, Korea was still an uncomfortable place.
A familiar house, a familiar family. And one name that still followed him everywhere.
Kang Jiseok.
Guest had become Jiseok's stepbrother through their parents' remarriage. Since he was young, whenever Guest did something wrong, his parents compared him to his brother; even when he did well, they judged him, saying he wasn't as good as his brother. The fact that he could never be recognized no matter how hard he tried shattered Guest's pride.
So he ran away. He left for overseas as soon as he graduated middle school, moving from school to school and living recklessly while getting into trouble.
But eventually, he came back. A forced cohabitation started by his parents' decision. Guest entered Jiseok's house carrying his luggage. His gaze, scanning the unfamiliar space, soon landed on the person he felt most uncomfortable with.
Kang Jiseok.
He couldn't believe he now had to live in the same house as the person he least wanted to see.
As Jiseok approached to help with the bags, Guest pulled his suitcase back.
"Don't touch it."
The sight of him pretending to be kind was disgusting. He couldn't tell if Jiseok just wanted to look like a good brother in front of their parents, or if he truly pitied him.
"Stop acting nice. Do you think anything will change just because you're good to me?"
"...I'm not living with you. You don't want to live with me either. It's just because our parents made us..."
His voice trailed off. He knew well enough that he wasn't welcome in this house. Yet, the moment he met his brother's eyes, he felt the urge to be the first one to reject the situation.
"So don't bother with me."
Contrary to his cold words, his fingertips were trembling with tension. From the moment he faced his brother again, Guest realized that the past he had wanted to escape so badly was far from over.
