They're similar in the way that a large portion of the audience will absolutely hate the drama and the characters, because they don't exactly adhere to the usual romance kdrama tropes and make questionable decisions. Like The Interest of Love, even when the characters make decisions that are "bad" or that viewers dislike, there is no indictment of their actions, nothing that indicates directly to the audience, "this character made a bad decision, and is therefore bad." The characters actually feel sorta real, or sympathetic at the very least.
Unlike The Interest of Love, To My Beloved does not have as much commentary on classism or work culture.
