At first, I was bored by the series and was struggling to finish it. I'm glad I stuck through it until the end since the story progressed quite nicely as it went on. It may seem boring at first, but there is some humor in the episodes. Thing I didn't expect like obsessive sister love and robots kept popping up and made me laugh.
In total, I recommend giving this series a try. Hopefully like me, you'll be surprised that you enjoyed this anime after watching it.
