There is too much competition. I am not referring to the timeslot since this is doing fairly well in Korea. It is second to You're Surrounded which will be difficult to beat. Lee Seung Gi is a rating monster and YS is fully a star studd castings. But if speaking internationally, the competition is fierce. Hotel King (My Girl fans), Angel Eyes (Big Bang VIP), Triangle (Lee Bum Soo, Jaejoong & Siwan from ZEA), Gapdong (Lee Joon), Dr. Stranger (Bora, Kang Sora, and the two leads) and on top of that they are have killer plots. So competition is very competitive. Do you know how fast the subs are going for Hotel King and Angel Eyes? Super duper fast, thats the perks of having famous idol actors.
