| Oh, a nameless flower | |
| Blossom in full glory | |
| Let it catch the light and soak in the sun | |
| In ordinary days | |
| I tried to reach out with this hand | |
| I got little. I had little, tried in vain | |
| I kept your smile just to myself | |
| Just to myself again before I realized it | |
| I don’t know why I never realized it until now | |
| All the small joy I could | |
| keep in my little mind is | |
| Not real happiness, far from happiness | |
| Now I know it’s too late | |
| Such a fool I am | |
| Baby, please tell me | |
| How can I get over you? | |
| I wish I could go back | |
| to the day when you were here with me | |
| Never take it away but give it away | |
| It’s the theory of happiness | |
| Another name for bravery | |
| I tried to open my eyes | |
| I got little. I saw little scenery | |
| I kept unknowing of the fact | |
| The more precious it is, | |
| the less we all can see it | |
| I should’ve told you “Thank you” | |
| and “I’m sorry” when I had the chance | |
| Like the air, had no presence. | |
| Finally, I knew it | |
| But I can’t breathe | |
| and live my life without you | |
| Oh, a nameless flower | |
| Blooming in full glory | |
| Dazzling like the days when | |
| I was here right by your side | |
| Hardly can find it. It covers us softly | |
| It’s the theory of happiness | |
| Another name for tender air | |
| My heart is like a rough | |
| stone rolling down the stream | |
| As time goes on, baby, just like the river flow | |
| Does the same to my mind | |
| Becoming round and round… | |
| Oh, a nameless flower | |
| Blossom in full glory | |
| I will never make the same old mistake again | |
| Your scent and color, everything of you | |
| Oh, I miss it, baby, | |
| really want it burnt in my heart | |
| Baby, please tell me | |
| How can I get over you? | |
| I wish I could go | |
| back to the day when you were here with me | |
| Never take it away but give it away | |
| It’s the theory of happiness | |
