In both dramas, the leads (FL in Anna and ML in Regeneration) were seen as the most promising student in their high school despite a humble background, but a transgression leads to their fall from grace, leaving them reeling. They both climb back up to the top again, telling lie after lie, before things start to crumble. In both dramas, they have a reporter friend who uncovers the truth, and both have dysfunctional marriages.
Both dramas are about a police agency dedicated to crimes committed by non-humans who coexist alongside people on Earth without them noticing.
