[Intro: Hongki]
Oh, a nameless flower
Blossom in full glory
Let it catch the light and soak in the sun
In ordinary days

[Verse 1: Hongki]
I tried to reach out with this hand
I got a little, I had a little, tried in vain
I kept your smile just to myself
Just to myself again before I realized it

[Pre-Chorus: Jaejin]
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

[Chorus: Hongki]
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
Nеver take it away
But give it away
It's thе theory of happiness
Another name for bravery
[Verse 2: Hongki]
I tried to open my eyes
I got a little, I saw little scenery
I kept not knowing of the fact
The more precious it is, the less we all can see it

[Pre-Chorus: Jaejin]
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

[Chorus: Hongki]
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

[Instrumental Break]

[Bridge: Hongki]
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
[Chorus: Hongki]
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

[Chorus: Hongki]
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
