Adorable!! <3 I've seen him in Big but he was even more adorable than I remember in Legend of the Blue Sea! I wanted to screenshot him every time. Great fashion too, in LOTBS. And I didn't know he had a guest role in HapiMari - I should maybe go and finish that just to see him ;).
I hope he would have a drama with Kim So Hyun (Let's fight ghost actress)..... He looks cool and cute in the "The Legend of the Blue Sea"....My Ghaaaaad! I think my heart is going to EXPLODE.... Literally!!
