the Korean Series

Recently, i have enjoyed some Korean series, but one thing they always have good begining but bad ending i can't bear.
Love is always the main topic in these seires for the coach potatoes. i can't force myself to see such a bad ending and so many tears from the chief actors and actresses.
I love the contents including so many moving stories, beautiful scenes--snow, meaningful symbols--trees or other things, the incidents--complex relationship of the roles, something happened but can't avoid, the actors, handsome gentlemen, cool guys, lovely girls, beautiful woman...So, you can't help falling in love with the Korean series.
But, i also wish good begining has an good end can have effects on the scripts.
If you are a fan of Korean series, share some experience with me.
