DC had captured this part of Park Si Hoo's expression in the flashback scene of Macau!
You remember when & why he made these expression?
When Seo Ahn asked him if they can go on a date
But he said they had worked to do....
And made her upset!
( He looked so clueless!^^ )
When Jin Woo told him no one else can be loyal to him as much as Seo Ahn
( Proud?^^ )
Before he will give her a necklace
(That love in his eyes is priceless!)
