The following are affirmatives, conjunctions, and other words that have similar sounds to "그래." I heard them a lot in a Korean drama named BLACK (highly recommended K-drama!). These words are also frequently used in other Korean dramas & movies.
BLACK is a Korean show with a mixing genre of horror, mystery, comedy, romance, action, and more. Black (a Grim Reaper) and Ha-Ram (who can see people's death) tackle to save lives together. I laughed a lot at the funny scenes, and couldn't hold back my tears for the last two episodes. Though I expected quite a different happy ending, I love the story overall. Full of foreshadowings that eventually connect.
