This, like a number of other K-dramas, starts with the protagonists as children, and then they make the leap to young adults in one episode. The children are great and it's a really promising start. I got totally sucked into it. Sadly, it's a long slide down from there. The characters develop illogically, with strong children becoming dishonest and whiny adults. The female lead is unbelievably boring and flat, with no personality at all. the male she was paired with as a child becomes a whiner. The plot becomes garbled and simply stupid. I"m at ep. 118 and I can't wait for the male lead to die, already. He's a terrible actor. The one bright star in this mess is Han Jung-Ho, who plays a disabled adult. It's the first portrayal of someone with a disability - probably intended as cerebral palsy - is never cringe-worthy and consistent throughout. He deserves a reward. The writer and the rest of the cast isn't worth mention. Why did I watch so much of this? I normally watch a daily dram to go to sleep to - and this wasn't even good enough for that. Now I just want it to end. Yuk.
