With the exception of Coffee Prince and Full House, I don't like the endings of all the dramas I've listed, hehehe. Not that there has to be a sad ending for me to like a drama (hard to believe I know, since I think I'm the only person who wasn't surprised by or who didn't hate the ending of that certain drama), but I prefer dramas that have a realistic, i.e. somewhat ambiguous, ending, like My Name is Kim Sam Soon (perhaps the best ending of any drama I've seen, but I wouldn't qualify it as a happy/cheerful ending) and Mary Stayed Out All Night. Yes, ladies and gentlemen, I LIKED THE ENDING TO MARY STAYED OUT ALL NIGHT. Cast your stones!
