With the premiere of these all-star dramas, the battle in the ratings department got intense, but it was KBS 2TV's 'Secrets' that managed to edge out the newbies this week. According to AGB Nielsen Media Research, the October 10th broadcast of 'Secrets' achieved a 14.6% viewer rating, which is 2.2% increase from its previous viewer rating of 12.4%.

As expected, SBS' 'Heirs' kicked off to a strong start with a 11.6% viewer rating, but dropped 1.1% to a 10.5% viewer rating for its 2nd episode. Following 'Good Doctor', it seems viewers grew tired of watching medical dramas as MBC's 'Medical Top Team' premiered in last place with a 7.3% viewer rating and later dropped 0.3% to a 7.0% viewer rating for its 2nd episode.

This week in dramas was definitely not short of fun, so which drama kept your hearts racing?
