I don't think Ahn Jae Hyeon was ready for a main lead yet!! He's done good at his minor roles but there's still…
to be great actor, he needs to practice of course. He can't just like that become very good main without trying, right? So be more forgiving and understanding for him
I hate "Goo Hye Sun", so I dont watch it yet, does the drama real good? can I give it a try?
hyesun may be irritating at the beginning but later she is getting better, so you shouldn't avoid it because of her [ps hyunwoo and luuvy are the best, you have to see it]
first 4-5 eps are so boring that you can feel resigned and dissappointed but later it becomes better and better, and luuvy! luuvy is the most important reason to keep watching it 8)
I don't agree that role play is bad and I don't get why you think jaehyun isn't good actor. I think that we shouldn't blame cast but those special effects and most of all plot, because it really sucks and makes us feel disappointed
