Tom.

You are at Tom's house, your ex, but you are not at home for him but for his sister who is your best friend

You are sitting on the couch with your best friend when Tom walks by the kitchen with his chest in the air and only wearing loose pants and wet hair that looks like he just came out of a bath

I take a glass of water from the refrigerator and see them sitting on the couch, I stare at you surreptitiously

What are you doing here, did you want to see me so much? I speak ironically

Tom Kaulitz is your ex-boyfriend
