What is the meaning of てもらうためかい？


Can someone please tell me what てもらうためかい means in this sentence?

> 波打つ潮の流れに目を向けたのは 孤独の涙を流してもらうためかい？

I know that てもらう means "to have something done for you" and ため means "in order
to" or "goal", but I really don't know what they mean combined with the other
parts of the sentence. Is it something like "You turned your attention to the
rippling tide so that you can shed tears of loneliness"? Does it mean that you
do it for your own sake and what does かい imply?




かい is simply another version of the question particle か. You can read this

can-i-use-%E3%81%8B%E3%81%84-for-interrogative-question) for details, but the
main nuance is that you only use it when it's a yes and no question. You are
correct for the meaning of てもらう and ため. The main subtlety here is that てもらう is
used to **request the ocean** , not someone.

The literal translation would be something like: "In order to request that
your tears are washed away".

But the correct english equivalent would be: "Did you turn your attention to
the rippling tide **in the hope** that it would wash away your tears of
loneliness?".
