It's about a girl in anxiety whether her beloved one will come to meet her, because it’s going to rain. "Footsteps are lightly taken, but they’re hurrying anyway. The thunder sounds like a lion’s roar, prompting a dispersion; what’s going on? That’s right, the rain is coming. I really hate the rain. I wanted to stay here a little longer. In an instant when the pleasant sensation has changed, when the lion makes me hurry, it's obvious. No! Annoying, it’s gonna rain!" If the boy didn’t come, then it’s going to rain inside her heart. "As for calls from him, nothing, and lessons from the rain too, nothing. If my mind would change, like the weather in England, that would be a relief, but it’s the opposite; it’s gonna rain!"
