Drama where lovers separate, then fall in love again

I’m in the mood for a Chinese or Korean drama where lovers have to part due to difficult circumstances and meet years later, falling in love again. Preferably, I would like the drama to be from 2015-2018. Thank you!

here  to heart is a brand new chinese drama

Winter Sonata. You already saw Autumn Tale, it's from the same director, year 2002. You should like it, it's very beautiful drama :) It doesn't fit your year's preference, but I really recommend it.
