Postscript: Color-coding by AquaChan; Translation by Hana.
Translator's Note: (kat tatum) Everytime I hear "jiriri" they are usually referring to the sound of a bell. I think the title is supposed to be about hearing that bell...  At the end [of the chorus] it's broken by saying an alarm clock woke them up.

女の　感です　恋の予感
キラキラ　している　甘い視線

夏はとても気が早いから
のんびりなんてしてちゃ　ダメ　だよ

眩しい　想い
つのるけれど
大人となる階段ね
眩しい　あまり
胸が　切ない
冷や汗　ジリリ　キテル

眩しい　愛しい
やけに　悔しい
大人ならば泣かないの？
眩しい　あなた
だけど　あなた
夏なら　ジリリ　キテル

眩しい　あなた
あなた　あなた
夏なら　ジリリ　キテル

It's a woman's feeling  A premonition of love
That sweet look is sparkling

Because summer is hasty
You can't relax at all

Brilliant feelings are inviting, but
those are the stairs to becoming an adult
In the brilliance, my chest is painful
I'm in a cold sweat... and then the alarm clock rings

Brilliant, beloved, it's awfully vexing
When I become an adult will I not cry?
Brilliant you, but it's you
If it's summer... then the alarm clock rings

Brilliant you, 
You, you
If it's summer... then the alarm clock rings
