[Verse : Kagamine Rin]
Hottest of season, the sun, so shining
There is no reason, be sad, complaining
Pick up all your things, don't forget the sunscreen
'Cause time is everything, so ignore your phone screen

[Pre-Chorus : Kagamine Rin]
In the sea, there's you and me
Coconut tree, swimming and free
Let's waste our time, this summertime
One two and three, sing it
Woo-hoo-hoo-hoo-hoo!

[Chorus : Kagamine Rin]
Na na na na na na
Na na na na na na
Na na na na na na
Na, woo-hoo-hoo-hoo-hoo!
Na na na na na na
Na na na na na na
Na na na na na na
Na, what a summertime!

[Verse : Kagamine Len]
Play it, your playlist, let's start the countdown
Light up the fire, sunset's going down
Nighttime has arrived, let's stay until midnight
Yeah nothing can stop us, it's gonna be alright

[Pre-Chorus : Kagamine Len]
In the sky, there's moon and stars
Lean to the car, smoking cigars
Cold ocean breeze, sipping good drinks
One two and three, sing it
Woo-hoo-hoo-hoo-hoo!

[Chorus : Kagamine Len]
Na na na na na na
Na na na na na na
Na na na na na na
Na, woo-hoo-hoo-hoo-hoo!
Na na na na na na
Na na na na na na
Na na na na na na
Na, what a summertime!

[Post-Chorus : Kagamine Rin, Kagamine Len, Both]
Would you walk with me? Sitting next to me?
Spend this day with me? Yeah? Woo-hoo-hoo-hoo-hoo!
Would you dance with me? Chilling next to me?
Spend this time with me? Oh, what a summertime!
[Bridge : Kagamine Rin, Kagamine Len, Both]
Summertime, a good time
Anytime, everytime
Summertime, a good time
'Til next time, woo-hoo-hoo-hoo-hoo!

[Chorus : Kagamine Rin & Kagamine Len]
Na na na na na na
Na, woo-hoo-hoo-hoo-hoo!
Na na na na na na
Na na na na na na
Na na na na na na
Na, what a summertime!

[Outro : Kagamine Rin & Kagamine Len]
Would you walk with me? Sitting next to me?
Spend this day with me? Yeah? Woo-hoo-hoo-hoo-hoo!
Would you dance with me? Chilling next to me?
Spend this time with me? Oh, what a summertime!
