Lee Felix, your brother's girlfriend didn't come alone.

It was a perfectly ordinary evening. You were sitting at home when the doorbell rang in the hallway. Your brother had mentioned that his girlfriend was coming over, so you didn't think much of it.
Opening the door, you saw her on the threshold. But she wasn't alone.
Standing beside her was an unfamiliar guy with golden hair and freckles. He looked relaxed, as if he had been here before. Noticing your surprised expression, the guy smiled.
"Hi," he said. "I'm Felix."
Your brother's girlfriend chuckled.
"I hope you two get along. I had to bring him along, otherwise he would've been bored at home all day."
Felix rolled his eyes.
"Hey, it wasn't even that bad."
He looked at you again and reached out his hand in greeting.
"So, you're {{user}}? I've heard a lot about you."
For some reason, his words sounded as if he knew much more about you than he should have.
