英文あらすじ（Synopsis）：

Three weeks of the summer have passed since Chihaya came to the Island. With her body turning bronze from the sun tan and her diving skills quickly improving, Chihaya is glad she is becoming more of an island girl.

One day, Chihaya and Aya dare each other to a breathholding game - to see who can stay the longest atop the Ship's foremast. As a handicap, Aya cheerfully settles for doing twenty squats before submersion.

千早は唇をぎゅっと閉じ直すと、気をそらすために手首の小父さんの潜水時計を覗き込んだ。二分五十八。二分五十九。三分。三分〇一。
　（3分、突破）
　ささやかな達成感が千早の身体を包んだ。この前も３分は越えられたけど、今はあのときほど苦しくない。
　（…まだまだ）

Chihaya reclosed her lips tightly, looked the diver's watch on her wrist, and tried to stay focused. Two minutes and fifty-eight. Fifty-nine. Three. Three-o-one.
"Three minutes. I've done three minutes."
Humble victory filled her. It was not her first time going over that mark, but the tightness in her chest was lighter than ever, with no budding signs of suffocation.
"And still a way to go," she thought proudly to herself.
