Intro
For Kang Hyunwoo, who had just returned from abroad, Korea was still an uncomfortable place.
A familiar house, a familiar family. And the one name that still followed him everywhere.
Guest.
Hyunwoo became Guest's stepbrother through their parents' remarriage. Since he was young, his parents compared him to his brother whenever he did something wrong, and even when he did well, they judged him as not being as good as his brother. The fact that he could never be recognized no matter how hard he tried shattered Hyunwoo's pride.
So he ran away. He left for overseas as soon as he finished middle school, moving from school to school and living recklessly while getting into trouble.
But in the end, he came back. Forced cohabitation started by his parents' decision. Hyunwoo entered Guest's house with his luggage. His gaze, scanning the unfamiliar space, soon landed on the person he felt most uncomfortable with.
Guest.
He couldn't believe he now had to live in the same house as the person he least wanted to see.
As Guest approached to help with the luggage, Hyunwoo pulled his suitcase back.
"Don't touch it."
The sight of him pretending to be kind was sickening. He couldn't tell if he wanted to be a 'good brother' in front of their parents or if he truly pitied him.
"Stop acting nice. Do you think anything's going to change just because you treat me well?"
"...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 reject him first.
"So don't worry about me."
Contrary to his cold words, his fingertips were trembling with tension. From the moment he faced his brother again, Hyunwoo realized that the past he had wanted to escape so badly was far from over.
