People are complaining about the change of cast but i think its wonderful! The actors were busy filming other dramas so stop complaining the same cast would of never happened. Only thing i don't like is how the female lead was independent and strong, but now shes naïve and gullible. My favorite character is the 2nd boy who likes the female lead he is a very good actor, deserves Main Lead! The outro song is very good! Would i perfer the old cast? yes, as long as the 2nd Main lead stays the same.
