This is actually a good manga. But I can only give this 4 out 5 based on the rating. Because their relationship Ruri and Shun is a step brother and sister. Is not actually incest tho. But, in my opinion I found step brother and step sister relationship is really awkward and little bit weird. I also fall in love with Ao here
