What a suspense

Starting what amazing. I like so Bong and Nam sin chemistry .Ye na has truly feeling towards Human Nam shin ,she deserve her bit she is half like her father .One because of her love towards shin she hiding everything otherwise she make everyone down in front of for .For her only shin is everything .All such scenario make me so curious to know at the end who become pair with Human Nam shin .Grandfather too good. I think he become bad person in front of everyone to find out who killed his son (Nam shin's father).That's why he indirectly help Nam shin's mother.
