Robin

And this episode started and we can see that Seo Jin and Ha Na has a past history.
The fact she remember keep asking to him about his necklace and if he saved her , cuz she remember of a guy who saved her when she was a kid, makes me want to know more about their past.
It's obvius they met each other, but who she knows is not Seo Jin but Robin.
This episode was good cause I can seems love beloved sung joon, who are playing a second male character as Tae Joon, what is a student of psychology, that is helping on searching of missing Doctor Kang.
After all Seo jin realize that Ha Na is in dangerous cuz she can be a murder of witness and go search for her in park wonder land. And there happens a thing that makes him transform himself in Robin again, and I can say I just love how Hyun Bin can act , you really can see a big difference between Seo Jin and Robin.
Now a just need wait for more episodes, I'm just excited about it :)
