Legend of Fragrance (2015)

Both female leads have extraordinary sense of smell and have a talent in making best and unique scent/perfume. Both fell in love with a rich male lead and have to overcome many obstacles to be together in the end. LJC sets in the modern era whereas LOF is in the ancient era.

60% similar plot, same era, and costumes.
While 'Blossom in Heart' main business is cosmetics, it is perfume in 'Legend of Fragrance' so even the settings with flowers, etc. is almost identical. The old family secret, lost love, revenge, and missing FL father is the same ( even the actor is the same LOL).
