[Verse 1: Wonhee & Minju]
Rain that fell all day
A day that was gloomy for no reason
Beside me, you
Smiling
Indifferently handing me your favorite ice tea
Your face where the dark clouds have cleared
Like it's sunshine, this time
[Pre-Chorus: Moka & Yunah]
You seem different
What only I can see
I like it so much
How come one by one
The more I get to know you
[Chorus: Minju & Wonhee]
This feels like sunshine, that sweet smile
I discover the hidden you anew every day
This feels like sunshine, perfеct, so fine
Even if you don't know, evеryone who knows will know
[Post-Chorus: Iroha, Yunah, Moka & Minju]
This feels like I-Y-K-Y-K, I-Y-K-Y-K, I-Y-K-Y-K
(If you know, you know)
I-Y-K-Y-K, I-Y-K-Y-K, I-Y-K-Y-K
(If you know, you know)
[Verse 2: Iroha, Wonhee & Minju]
I can't see it all when you are next to me
Sweetness hidden behind your expressionless face
Indifferently and carefully observed all day long zoom
My heart pounds at your absurd actions
Your secret affectionate side is a bonus
I bloom at your hidden smile
The more I get to know you, the more I'm attracted to you, boy, oh
[Pre-Chorus: Iroha & Yunah]
You're like a hidden café
I met you by chance on a walk
I'm falling for you more and more
The more I get to know you
[Chorus: Wonhee & Moka]
This feels like sunshine, that sweet smile
I discover the hidden you anew every day
This feels like sunshine, perfect, so fine
If you don't know, you don't know, but everyone who knows knows
[Post-Chorus: Yunah, Iroha, Moka & Wonhee]
This feels like I-Y-K-Y-K, I-Y-K-Y-K, I-Y-K-Y-K
(If you know, you know)
I-Y-K-Y-K, I-Y-K-Y-K, I-Y-K-Y-K (If you know, you know)
