いつ戻ってくるかもわからない隣の車のドライバーさんを待つわけにもいきませんしね。
心という器はひとたび、ひとたびヒビが入れば二度とは・・・二度とはッッ・・・

It's not like I could wait for the driver of the neighboring car; there was no telling when they'd get back.

Once...once cracks have been made in the vessel called the heart, then never again...never again...
A memetic quote from the manga Shigurui/Death Frenzy.
