Song meaning of Durch Den Monsun by Tokio Hotel

Oh boy, where do I even begin with this one? "Durch Den Monsun" by Tokio Hotel seems to be about a guy who's locked himself in a room that's both empty and full of memories of his ex. He's waiting for something, possibly for her to come back, or maybe just waiting for the rain to stop so he can go outside. He's got this weird obsession with half moons, which makes me wonder if he's also into werewolves or something. Anyway, he's determined to face the storm, walk along the edge of a cliff, and fight some mysterious forces that are keeping him from his ex. But he's not doing it alone, oh no. He's got this grand idea that they're gonna run through the storm together, because apparently, storms are a great way to rekindle a relationship. And why do they need to go through the monsoon, you ask? Well, duh, because then everything will magically be okay! It makes perfect sense if you don't think about it too hard.
