雨　風も　天の思(おぼ)し召し
心をずいぶん鍛えてもらったわ
どうにかこうにか　I can do

いきなり君の登場でね
その時歴史が180度「ターン」

スイピョン泳ぐ
イルカのように

人生うまくすり抜ける彼はさすがで

と　宣(のたま)ひける

もう!　すっちゃかめっちゃか〜
YOU!　大好きすぎる
右のフック　左アッパー
そうだ　恋のパンチをお見舞いすんどぉ〜
そうだ　大人だけに好き勝手させない

ame kaze mo ten no oboshimeshi
kokoro wo zuibun kitaete moratta wa
[No/Ta/As] dou ni ka kou ni ka I can do

ikinari kimi no toujou de ne
sono toki rekishi ga hyaku-hachi-juu-do "TAAN"

SUIPYON oyogu
IRUKA no you ni

jinsei umaku surinukeru kare wa sasuga de

[Mo/Ka/Sa] to notamaikeru ([No/Ta/As] keru keru keru)

[Mo/Ka/Sa] mou! succhakamecchaka~
[No/Ta/As] YOU! daisuki sugiru
migi no FUKKU hidari APPAA
sou da koi no PANCHI wo omimai sundoo~
sou da otona dake ni suki katte sasenai

The rain, the wind, and the heavens are doing as they please
And my heart's been strongly fortified
Somehow or another, I can do it
 
Suddenly you made an appearance
At that moment, history made a 180-degree turn
 
Swimming smoothly
Just like a dolphin
 
There's no doubt that he'll be slipping through life pretty smoothly
 
I make that declaration
 
Well! It's so jumbled up~
You! I'm too much in love with you
A hook with the right, an uppercut with the left
That's right, I'm calling on you with a punch of love
That's right, we can't let only the adults do as they please
