Previously, it was confirmed that actress Lee Yeon Hee would be replacing original cast member Kim Hee Sun for season 2, due to Kim Hee Sun's conflicting schedules. While Kang Ho Dong will be returning again for season 2, the other original cast member CNBLUE's Yonghwa is currently carrying out his mandatory military service and will not be able to join. 

Yonghwa's spot will be filled by none other than Lee Soo Geun, and filming for 'Island Musketeers' season 2 is set to begin some time this month. Season 2's premiere date has yet to be determined.
