Queen of tears (Netflix series)

Marriage of the century... war of the century?" The third generation of the Queens Group conglomerate, the queen of department stores, 'Hong Hae-in'. The son of the head of Yongduri, the supermarket prince 'Baek Hyun-woo'. A dizzying crisis and a miraculous restart of a love story of a couple in their third year. It's a very good drama with many comical and tearful scenes in each episode. 

The BGM music is also very good.
