According to AGB Nielsen Media Research, the December 5th episode of SBS' 'Heirs' achieved a 23.9% viewer rating which is a 2.5% increase from the previous day's rating of 21.4%, breaking its own record.

MBC's 'Medical Top Team' has been struggling in the ratings department but managed to maintain its 2nd place spot with a 5.8% viewer rating which is a 0.4% increase from its previous rating of 5.4%. Although numbers like these would usually put a show dead last, the show managed to stay second thanks to the extremely poor ratings of KBS 2TV's 'Pretty Man', which dropped 0.5% from a 4.3% viewer rating to a new low of 3.8%.
