Two new dramas premiered Thursday night, kicking off a new competition in the drama viewership ratings for the Wednesday-Thursday time slot. These are MBC’s spy romantic comedy Terius Behind Me and SBS’s medical series Heart Surgeons, with the latter emerging as the victor in terms of TV viewership.

According to Nielsen Korea, Heart Surgeons came in first in the said time slot, garnering nationwide audience shares of 6.9 percent, 7.5 percent, 6.2 percent, and 6.5 percent (average=6.8 percent) for its four episodes that had been broadcast. These ratings beat what Terius Behind Me has managed to obtain, which stand at 6.3 percent, 7.2 percent, 6.1 percent, and 6.1 percent (average=6.4 percent). Heart Surgeons is ahead of Terius Behind Me but both dramas are essentially neck and neck. Both shows aired four episodes on their first night of broadcast to catch up with the schedule as MBC and SBS decided not to air two episodes on Wednesday due to the Chuseok holiday.

Heart Surgeons, tells the life story of three thoracic surgeons in a hospital, centering on a fellow (played by Go Soo) in the thoracic department who has a mother waiting for a heart transplant and a renowned thoracic surgeon (Um Ki-joon) with a humble educational background. Terius Behind Me, on one hand, follows the story of a black ops secret agent (So Ji-sub) who ends up working with his widowed neighbor (Jung In-sun) on getting to the bottom of a large-scale conspiracy involving her husband.

Meanwhile, KBS2’s The Ghost Detective came in third place for the evening, recording 2.6 percent for both its two episodes.
