Foreign film – Older man arranges for asian woman to be his wife – She dies suddenly?

Sorry folks,

This one’s popped in my head and I can’t for the life of me recall what it was.

I’m fairly certain it was a foreign film having watched it with subtitles. I recall there was some sort of arrangement/deal made for this man to take in a woman to be his wife? She moves in with him, there was a language barrier between them so it was difficult for them to communicate in the beginning but as they spent more time together they’re relationship was progressing. She hides the fact she’s been taking some sort of medication for an illness/medical condition and dies suddenly towards the end.

You’re my only hope. Thanks in advance!
