If you’re after…
If you’re after is a nice way to say if you’re looking for something or if you want something. It can also be used if you’re looking for someone. And if you’re looking for someone after your own heart, this means you’re looking for someone who has similar likes and ideas to you.
Examples
“If you’re after a quiet place to go for a walk, I’d recommend going to the woods.”
“I’m after the headteacher, have you seen him? Yes, he’s in the playground.”
“As it’s so cold this winter, I’m after a new coat.”
“You make the best apple pie ever. You’re a man after my own heart.”
