The plot for this series is simple, yet it was made complicated for some silly reasons. At the beginning, the audience were presented with a conflict which didn't have any explanation yet. As the plot progressed, a series of flash backs unfolded the mysteries one by one. This series relies on these flash backs a lot. I think it's okay to use flash backs as a tool. It's just that you need to make it clear to the audience. Because if it went on for too long, it can get confusing easily. The acting from most actors were good. There was no unnecessary scenes which gets dragged on just for the sake of fulfilling the quantity of episodes. Which is a good thing, cause that means that this series is not boring. Although it's not as interesting as Bed Friend, it's still good to watch. For fujoshis, this one must be put in your watch list.
