You better take it from me; that boy is like a disease.

You're running, you're tired, you're trying to hide, and you're wondering why you can't get free.

He's like a curse, he's like a drug; you get addicted to his love.

You want to get out, but he's holding you down cause you can't live without one more touch.

She told Lily again and again that he was no good for her. She'd already been through it. Scorpius was a pig. He was a womanizer who really knew how to play the game.

But Lily was too far-gone. She'd been dating him for a solid month. Lily had always fallen hard fast. Rose couldn't stand to see her cousin get hurt. She was going to have a talk with Scorpius.

I see that look on your face; you ain't hearing what I say, so I'll say it again cause I been where you been

And I know how it ends; you can't get away; don't even look in his eyes.

He'll tell you nothing but lies, and you'll want to believe,

But you won't be deceived, if you listen to me, and take my advice.

Rose knocked on his door. Several seconds later, it opened to reveal his piercing blue eyes. She remembered exactly what those eyes could do to a girl.

"Rose," he drawled.

"Scorpius." She brushed passed him through the door and sat on his sofa.

"And to what do I owe this honor?"

"Well, I won't be beating around the bush. You're dating my cousin Scorpius. I know what you do to girls when you get bored, and I assure you that if you hurt Lily, you will wish you had been born a girl."

He raised his eyebrows, a smirk on his face. "I always did love that fiery temper of yours." He sauntered over to her and pulled her to her feet. Still smirking, he leaned in and gave her a kiss full on the lips.

Lily, who had a key to Scorpius's flat, walked in at that moment.

Run, run away don't let him mess with your mind.

He'll tell you anything you want to hear.

He'll break your heart, it's just a matter of time.

But just remember:

Rose jumped away from Scorpius, her face red and murderous.

Lily stood in the doorway, her expression blank.

"Lily! It isn't what it looks like! Your cousin barged in here, demanding that I leave you and take her back. Then she –"

"Scorpius, don't even bother. I was standing right outside the door the whole time. Rose was only here to warn you not to do exactly what you just did." Lily walked over to Rose's side and took her hand. "Bring my things to me at Rose's flat by the end of the week. I'll do the same." With that, the cousins walked out of the flat.

He's a good time cowboy Casanova leaning up against the record machine.

He looks like a cool drink of water, but he's candy-coated misery.

He's the devil in disguise, a snake with blue eyes, and he only comes out at night.

Gives you feelings that you don't want to fight,

You better run for your life.
