I've got a rainbow in my heart!

我看到了心中的彩虹。

You are the rainbow in my heart.

你是我心中的虹。

You are the rainbow that glows in the sky of my heart. The lullaby that sends me to sleep. You are a good news to my ears. A perfect reason to dream of tomorrow.

你是我心中犹如闪耀在天边的彩虹，你是一首轻柔换我入梦的摇篮曲，你是荡漾在我耳旁的一个令人兴奋的消息，你是我继续明天梦想的充分理由。

Like that rainbow which makes my heart leap up, life springs up in all its terrifying beauty, and then fades away into the nothingness from which it sprang.
