I'm actually a bit surprised by all the negative reviews.
Because of them I went into the series with no hope really and I absolutely enjoyed the series.
Yes, it isn't as high standard as the famous BLs but I think it is a nice one to watch if you want a slightly lighter story. The only 8 episodes guarantee that you won't get bored and yet is the development of the characters at the right place and things don't feel rushed.

All I can say is, please give it a try and get into a few episodes. It is a light and heart warming story which has got its rightful place amongst all the other BLs.
