結局3度寝しちゃったわ
どうしよう　急いで支度して
スッピン飛び出しバスに乗る
間に合いそう　「ふう」

あらやだ　気になるあいつだわ
「最悪」　寝癖も気になるわ
会釈したけど　来ないでね*
恥ずかしすぎる

青春ど真ん中　花の十代
毎日我武者羅に　生きてるんだな
夢は大きく華やかに
でも　今は
お腹がGOO〜

「なんだよ」　やっぱりこっち来た
乙女の恥じらい気がつけよ
態度がでかくて　声もでかい
話してく　「なぁなぁ」

こいつの　良いとこ　こういうとこ
会話がうまくて　乗せられちゃう
やっぱり突っ込み入ったよ
寝癖の私

青春ど真ん中　花の十代
素直になれなくて　恥じらう世代
恋のイロハも勉強中
バスの中
至近距離〜

青春ど真ん中　花の十代
素直になれなくて　恥じらう世代
こんな朝もたまにゃいいか
でも　今は
独占中

結局　ずいぶんしゃべったわ
学校じゃ　こんなことあり得ない
心の中確定した
恋に落ちました

I fell back asleep again 3 times
What should I do? I quickly get ready
I hop on the bus with no makeup on
Seems like I'll make it! *phew*

Oh no, it's that kid who I like
"Why me?" I'm worried about my bed hair
I said hi to him, but please, don't come!
I'm too embarrased

In the midst of youth, the lovely teenage years
We live each day without worrying
I keep my dreams big and glorious
But right now
My stomach is growling~

"What do you want?!" He came here after all
Can't you tell when a girl's embarrassed?
His attitude and his voice are huge
And he's talking to me "Hey!"

This is what's good about him
He's good at talking, and I can keep up with the conversation
But I had to cut his jokes
Me with my bed hair

In the midst of youth, the lovely teenage years
A generation that's embarrassed because we can't be honest
I'm studying the basics of love right now
Inside the bus
I'm so close to him~

In the midst of youth, the lovely teenage years
A generation that's embarrassed because we can't be honest
A morning like this might be good once in a while
But for now
I'm having you all for myself

After all, I talked to him
This definitely couldn't happen at school
I decided it in my heart
I fell in love
