This harem/romance manga starts off in a pretty cliché fashion but I assure you that this manga is a great example of how cliché's can be done well if they are written well.
Once Yuu moves in with the Mikadono sisters it is easy to write this off as another stereotypical harem/romance manga that devolves into the sisters falling for Yuu despite him being so inept at everything (besides cooking). It would have been very easy for the mangaka to make that kind of story but instead, what we get is a very wholesome and unique set of chartecters with their own personal struggles and comedic shortcoming. While the sisters may seem perfect on the surface, we come to learn that they are deeply flawed in their own personal lives with Yuu slowly becoming a pillar in supporting their day to day lives with his positive attitude and caring nature. While Yuu may be inept, his greatest support comes from giving the sisters a sense of family they didn't know they lacked. That is the strongest point of this manga (well that and the extremely cute tomboys). The relationships that develop not only between Yuu and the sisters but also among the sisters themselves was such a joy to read. You just want nothing but the best for each of the sisters and I believe that if a manga can make you feel like you don't know which character you like the best, it is doing something right. I especially loved the art style of the female characters as they felt very distinct and well drawn. I urge anyone whose thinking of giving this manga a try to do so as this is a rare example of a cliché done right.
