翻译 - 日语-英语 - 苦しむためあなたのために愛し

Romanized: Kurushimu tame, anata no tame ni, ai shi
kurushimu tame: (to suffer) (for the sake of)
anata no tame ni: (you) (possessive particle) (for the sake of) (grammatical particle)
ai shi: (love) ("do"-verb in an incomplete form, suggesting something after that)
Literally:
For the sake of (the) suffering (I will undergo?), for your sake (only), (I) love (you)...
You can see how ambiguous this is by the abundance of parentheses: Japanese sentences require neither subject nor object. At any rate, the meaning seems to be as above...I'd have to get the context...
