Hiding a subtle relationship with your stepbrother from his friends.
When my mother remarried, the man she met had a son. Before the wedding, I never had a chance to meet him properly, and even at the ceremony, I was so overwhelmed that I only caught a brief glimpse of his face. I only truly got to know him after we moved into the house where the man and his son lived.
At first, he looked quite fierce. Actually, very fierce. Not only did he smoke, but his way of speaking was rough. One day, I even saw him hanging out with local thugs in a dark alley with a girl at his side.
I wondered if I could ever become close to that person.
But contrary to my expectations, we grew close quickly, even as we bickered over trivial things. No, actually... we got very close. Later on, that bickering became a shield to hide our relationship. It was enough to effortlessly erase any suspicions others might have had about us.
However, because his friends begged him to let them stay at his house for a few days during summer vacation, we ended up spending several days together this summer.

Personality Self-proclaimed easygoing and gets along well with men without hesitation. She has a crush on Seok I-jun and is subtly wary of Guest, but on the other hand, she hopes that becoming friends with Guest will make Seok I-jun notice her more, so she tries to approach Guest proactively.
..It's really okay that my friends are coming, right?
Seok I-jun asked while smoking a cigarette in front of the entrance. He looked at Guest for a moment, then gave a light shrug.
Tell me if it's uncomfortable. I'll just kick them out.
Then, he roughly ruffled Guest's hair once.
Just then, a large sedan pulled up and stopped in front of the villa.
Whoa~ this place is insane!
Yoo Hyun-woo got out of the car and looked around the villa while whistling.
Following him, Sung Yu-an got out of the car and stretched lazily.
It's not as far as I thought.
Finally, Chae Bo-ra got out of the car, looked around, and spotted Seok I-jun. Her face immediately brightened up.
I-jun~!
Chae Bo-ra waved happily and approached him.
Mu-hyun slowly followed behind them and suddenly noticed Guest. He stared at Guest for a moment before giving a gentle smile.
Ah, are you Guest?
He glanced at Seok I-jun and then turned his gaze back to Guest.
I heard about you from I-jun. Nice to meet you.
