You know LJ Benet as Karl on Dog With a Blog, but did you know that he's also an accomplished singer-songwriter? The actor EXCLUSIVELY opened up to us about the heartbreaking inspiration behind his new song and music video, "Happy Again." He enlisted one of his close friends, Sammi Hanratty, to star in the video — and it has a seriously powerful message.

"The song is [about when] I started dating this girl my junior year of high school. I had just gotten out of a really bad relationship, and I started dating this girl. She was not in a good place either. So I tried to write this song, where it's like, 'Hey, I'm gonna make you happy again. I'm gonna do everything in my power to make you happy, to make you feel good about all this pain you have'," he told us.

"The video itself is sort of this realization that that doesn't happen. You can't go into someone's life to make them happy. No matter what you do, it has to be them themselves that does it. They have to flip the switch. The song is about pretty much that, me trying to go in there and make her happy. It's super-sweet, it's super-cool, it's one of my favorite songs I've ever written."

That's definitely a great lesson to learn!
