We can add Revolutionary Love. I dropped this ongoing kdrama after ep. 2, when a rich father kept hitting his adult son, who was laying on the floor, until that one began bleeding, in front of many people who were just passively watching and not even interfering. That sick father wanted to continue hitting him further with a chair, but was finally stopped.
Many of us were shocked in the beginning and commenting about on Dramafire. But the producers fixed it in the end, they made his wounds happening by accident, from falling on his face.
Last update regarding the cast and Jung Hae In playing in this drama:

It's for sure the Best Chinese Drama ever!!
PS Appreciating the quick uploads on YT after the broadcast.
That song, How Long Will I Love You, is from About Time soundtrack, the movie about a time traveler. Wow.
