The main characters in both dramas have to act as their doppelganger from super rich-rich family with evil family members. Pretending to be the other person, they also have to take over some big business company. The overall mood and atmosphere of the shows are quite different, though.

Both dramas have fast-paced romance. Also while watching I was equally puzzled. These dramas don't suit my taste but they had similar vibe, so maybe you can enjoy one of these dramas if you liked the other ¯\_(?)_/¯

The FL is a short track speed skater, one of the MLs is a figure skater. The story is about sports and following one's dreams

These two shows have different atmospheres but they are similar in a way that in "Come and Hug Me" main hero's father killed parents of main heroine :(
