The little Romeo that could has found his subway sweetheart.

Patrick Moberg, a Brooklyn Web designer who embarked on a multimedia quest to find the rosy-cheeked straphanger for whom he fell on the No. 5 train, says he has managed to track down “the woman of his dreams.”

“When I was walking to work today, I suddenly realized, wow, this is insane,” said Moberg, 21. “New York has a ton of people. I don’t know how this worked. It was less than 48 hours. I’m amazed by how quick I got a response.”

The “mysterious brunette” from his Sunday subway ride is actually Camille Hayton, a BlackBook magazine intern from Melbourne, Australia.

“This is crazy. I can’t believe it’s happening,” said Hayton, 22, of Brooklyn.

The two have e-mailed back and forth and plan to meet for a cup of coffee this weekend.

“We’re just going to chat,” said Moberg. “I just want to know how she reacted to all of this.”

On paper, they seem like a decent match.

He’s obviously a die-hard idealist with artistic tendencies, while she said on her Facebook page that she loves “anything romantic” for movies. Moberg said he’s gotten loads of responses ever since he created the site dedicated to finding Hayton after he spotted her Sunday on the train.

On nygirlofmydreams.com, he drew a picture of the girl who captivated him, with blue shorts, black leggings, and a red flower in her dark hair.

He must have been seriously smitten, because he also posted his cellphone number and his e-mail and begged the public to help him find his lady love.

Soon enough, his inbox was brimming with letters, and his phone was ringing off the hook.

“Some people said, ‘I’m not the girl, but you’re so adorable, pick me instead,’ ” Moberg said.

But he wasn’t tempted, and his patience paid off Tuesday night.

A friend of Hayton’s texted him and said he recognized her from Moberg’s drawing.

“I kind of dismissed it because I got so many e-mails like that from people,” he said.

“I replied back and said that would be amazing if you could contact her and then I let it go.”

But a little while later, an e-mail came to him with a pic of the fetching Hayton, asking, “Is this your dream girl?”

And it was.

“I replied back and said let me know if she’s OK to catch up,” he said.

Hayton – a theater, art and photography student who graduated from University of California at Santa Cruz – wrote him that “she wasn’t sure if she would live up to my expectations and I said ‘There are no expectations,’ ” he said.

Sadly, he might have to comfort his new gal pal. Her home in New York was burned to the ground a few weeks ago, according to friends.
