I feel like I wanna explain further what it's about so here's the meaning.
[First & second stanzas] There was this guy in my class who used to bully me. And when I was a kid, he really scared me because he was one of the strongest guys in class. Because of the bullying, I became more insecure. The metaphor of red riding hood carrying the gun around represents how I cut everyone off and became more defensive, while saying that I had "gotten used to the bullying" and got stronger. I was actually at my weakest.
[Third stanza] This is about what happened now. Recently, he apologized to me. He said he bullied me because it made him feel better that I was weaker than him. And I've been thinking about it lately. I never really thought of him as a human being, but more of a monster. But now, I see that he's changed, and the entire time, he was just some guy who wanted to be somebody.
And now I see that I was stronger before, that before, I had the guts to show emotion. I had the guts to be myself while not shooting anyone down.
