love is an unfortunate fate; you can't help falling in love, no matter the consequences
Proverb expressing that love is beyond reason and often brings suffering, but one cannot escape it. Used to resign oneself to the hardships of love.
It's the fate of being in love—I end up going along with her selfishness.
惚れたが因果とはよく言ったもので、彼のためなら何でもしてしまう。
As the saying goes, love is an unfortunate fate; I'd do anything for him.
