I got into kdrama world early in 2018 and I remember watching a series where the leads like each other, there is some sad past to both which I can't clearly remember but they talk about a plum tree in the MLs backyard. The they split up because the ML goes abroad with a promise to return but never does. I think he passes away but the FL is unawares till the MLs brother organizes some art show I think. I have been trying to find the name of this drama for a while but I'm not sure if I'm combining multiple dramas or if there is actually a series with this storyline. Would be nice to get the name if there is actually a drama like this
