| I close my eyes and | |
| 遥か遠くに見える空 | |
| 限りない夢を詰め込んで 今旅立つ | |
| Winter or Spring Summer or Fall | |
| 気付かずに 不安を隠してた | |
| Won't you take me in your heart | |
| 交わす言葉 暗い道 照らす | |
| You will always have the key to my heart | |
| 通り雨が 優しさに変わる | |
| ねぇ悲しみがあるから 強くなれる | |
| 君と行くよ 明日への果てしない旅 | |
| Won't you take me in your heart | |
| I only I only want to be with you | |
| You will always have the key to my heart | |
| I only I only want to be with you | |
| Baby you're the key to me | |
| Open up and you will see | |
| I'll always be right there | |
| You know I will, and you know care | |
| Don't need a fancy car | |
| I like you just the way you are | |
| You know it's plain to see that you're the only one for me... |
| I close my eyes and | |
