Hello! I watched a jdrama about six months back and have been searching for it ever since but haven't been able to find it, so I figured I would give this a shot. Sorry if the description sounds a little strange, I can't remember all the details.
From what I remember, it involves five women in their forties who are all friends, but one of them dies in the very first episode. I believe it was a boat accident in Canada, where she was on vacation with her husband. The remaining four then realize how short life is and resolve to find their own love stories. One woman falls in love with a boxer, one of them falls in love with her daughter's tutor (who is a wolf in sheep's clothing), and one of them falls in love with a doctor at the hospital where she works (this is the one I'm most unsure of).
Any help would be much appreciated!
