I’m pretty lenient when it comes cameo appearances in dramas, it’s solely service and as long as it’s not a jarring schism in the narrative then it’s fine to do. The Hong Sisters are well known for their cameos in their dramas mostly from prior stars who have done their dramas in the past. Jang Geun Seok has done two Hong Sisters dramas, as the memorable second male lead in sageuk Hong Gil Dong and the even more memorable male lead in You’re Beautiful.
It’s been a decade since he worked on their dramas and I wish he did his cameo earlier than making an appearance in last weekend’s episode 3 of Hwayugi. He played a preening peacock demon who is an actor and boy was I underwhelmed with his appearance. All the charisma of his YB days are gone especially since he was styled as a throwback to Hwang Tae Kyung, Of course this was just a short 5 minute scene and for his fans there will be a long drama to follow forward as he;s signed on to be the titular Peacock King for the next SBS Wed-Thurs drama.
