カリブーは悩んでいました。
どれだけ働いても、続いていくのは同じような毎日。
どんどん過ぎていく時間、残っていく疲労。
会社で任される仕事も増え、眠る時間が減り、自由に過ごせるあいだはもう殆どありませんでした。

Caribou was worried.
No matter how much he worked, the same kind of days continued.
Time rolled on and the weariness stayed.
The work he was responsible for at the company increased, his time to sleep decreased, and he had almost no room to live as pleased.
