romance drama with an older couple

I am trying to find a good romance drama with an older couple. The last good Chinese one I watched was The first half of my life. The storyline does not have to be like that but that's what I mean when I say an older couple :) 

- I have a lover

- The good wife

Love Story 2001

The Flower Shop Without Roses

Second To Last Love 2012 Season 1, 2
