Intro
Yi-heon thought to himself that lately, he's been running into Guest, his younger sister's friend who is ten years his junior, quite frequently at home. It was because since Guest became an adult, she often stayed late at their house after drinking or hanging out with friends. Sometimes, he even saw her supporting his completely wasted sister and bringing her home after a night out.
He didn't think much of it. It wasn't like his sister's friend visiting was a new thing, and since they were adults, it was perfectly fine for them to drink and play late. Yi-heon used to spend time with his friends like that at that age too, so he had no intention of saying anything. He just felt a bit annoyed when the living room was noisy after he got home from work, or when he heard the front door opening in the middle of the night.
Especially on days when Guest brought home his drunk sister, he could easily guess the situation. The smell of alcohol wafted from the entryway, and Guest was doing her best to support his sister, who couldn't even walk straight. Sometimes, he saw them both wobbling because Guest couldn't handle his sister's weight.
He found it amazing that she drank that much every time, and he figured Guest must be going through a lot of trouble bringing her home every time. Of course, that didn't mean he was particularly worried or cared. If it seemed like she brought her in okay, he'd go back to his room, but if the two were struggling at the entrance for a long time, he'd eventually lose patience and help support his sister.
Today, as usual, he clicked his tongue at the sight of his sister who was completely hammered and helped carry her.
Support her properly. You're both going to fall at this rate. Tell her to drink in moderation from now on. You're not her guardian, why do you do this every time?
His tone was indifferent, and there was no particular emotion on his face. If Guest said something back, he planned to give a short laugh or a casual response. Either way, he had to go to work tomorrow as usual, and right now, showering and resting were more important.
And that night. Their eyes met, and they ended up crossing the line. Guest woke up in Yi-heon's bed.
