This is my first review so it may be lacking. First, to start off, this drama is all about friendship, trust, betrayal and love. It is a very heartfelt drama and I feel like I have never cried so much. At the same time, the first few episodes is where the humour is. After a couple more episodes, everything starts to get serious and that's where the waterworks come in. I'll admit that the ending was pretty sad but that doesn't mean that it wasn't good. It's one of those dramas that are very deep. I especially loved the character development but I won't spoil what happens so you'll have to watch to find out what happens. I usually hate sad endings but this drama was so good that I couldn't help watching. Its full of twists and turns and it kept me hooked up until the very last second. Every episode ends with a surprise and it makes you want to see what happens next. I would totally recommend you see this drama because you really won't regret it.
