The two deals with mandatory military in a very harsh way, D.P. is dark with some comedy, The Coast Guard is bleak and crazy.
Two taiwanese drama with beautiful journey and breathtaking scenery, kind of slow and slice of life. Two young women who search theirs path in life and finding herself. A healing story.
Basically while everything is different, it's about the exact same story. A very lonely boy/man who search to escape his reality. And they have the same ending.
