As the song says, when you're accidentally in love there's no escaping it. Some people are polar opposites, others are too alike, and some just outright hate each other.
But whatever the reason may be for their differences, there are many characters on television who fall for the person that they would least expect. These relationships keep the audience on the edge of their seat and make for some of the most entertaining (and ironic) romances on television.

And let's be real, who doesn't love some good relationship development?
Below is a slideshow featuring 31 couples who accidentally fell in love with each other.
Lucifer and Chloe - Lucifer
It's safe to say that Lucifer and Chloe didn't fall in love on purpose. But after going through what these two have, it's insane that they didn't get together sooner.
Clarke and Lexa - The 100
Considering they started off as leaders on opposite sides of a war, it was definitely an accident that Clarke and Lexa fell for each other. But you can't help who you love. With much to learn from one another, their relationship ended up changing both Clarke and Lexa for the better.
April and Jackson - Grey's Anatomy
Jackson and April were friends for seasons before anything actually happened between them. Jackson was always protective of April but it wasn't until later in the show that they realized they were a lot more than friends.
Jackie and Steven - That '70s Show
Jackie and Steven are a couple that deserved better. Their relationship was an unexpected surprise and despite their bickering, they were just right for each other.
Logan and Veronica - Veronica Mars
Logan and Veronica are another example of a couple who went from hate to love. Although they didn't like each other at first, they ended up falling head over heels for one another.
Barney and Robin - How I Met Your Mother
Robin was in love with Barney's best friend and Barney was the type of guy who hated relationships. In fact, he hated them so much he even made a video for his friends begging them to get him out of any future relationship he may be in. But for some reason when Barney and Robin fell for each other, it made perfect sense.
