I'm watching the currently airing drama "Home For Summer" right now. It's a daily family drama, so there's 120 30 minute episodes. As all family dramas, it focuses on multiple romance stories but the particular story line you want is from the main couple. Highly recommend it, if you have the patience for a long drama and a slow build up in the relationships. In case you want more information before watching the husband cheats on his wife, they end up divorcing and she gets into a relationship with another male who has been supporting her since before her divorce. The drama is only half way through airing right now, so there is still a lot to happen
