A Date With Carter

You look out the window and see a white truck with a familiar blue logo on the side. You might as well get up. You have nothing to do right now anyways.
You stand and stretch your arms into the air, wincing a little when you hear them crack. After popping all your joints, you open your door again and head out to check your blue mailbox.
Inside, you find a black envelope sealed with a glittery red heart sticker. What the heck? You're single and you don't have any admirers that you know of. Huh. It won't hurt to look.
After stepping back inside your house, you take out your letter opener and look at the letter. It's a piece of navy construction paper folded neatly to fit into the envelope. Cool.
You open the paper, sitting back down into your red leather chair. The words are written in a sparkly pink pen. You start reading.
"Dear Y/N,
After weeks of struggling, I finally found your address~! Care to go on a date with me?
Love,
Carter"
You frown, and reread the note. And again. And again. What. The. HECK?! You know a lot of people, and you definitely don't know a Carter. And he found your address somehow?! The HECK?!
You tap your foot on the ground, thinking. On the back of the letter, there's an address. Squinting, you see a warning at the bottom right corner.
"If you don't come I'll blow up your house <3"
That's…weird. Scary. What now?!
