A crush is by definition: Puppy love, also known as a crush, is an informal term for feelings of romantic or platonic love, often felt during childhood and early adolescence.
I have this for someone. It's terrifying. There's something about them that makes me want to be with them all the time and I don't understand it.
I really like this person and I wouldn't even say it's a crush anymore at this point.
And the best part is,
THEY LIKE ME BACK!
