If you're into unrequited love, I'll definitely recommend it. And yes, it is on the border of incest as well. This series doesn't follow the stereotypical romance anime plot. This is gonna be more true to life than you can imagine. The protagonist is a person who is not perfect by any means. He constantly makes stupid decisions that are frustrating. But that's the point of the series. In real life, you're not always going to make the right decisions. That is especially true if strong emotions of unrequited love are involved. Not to mention the fact that he does whatever they can to avoid hurting his step sisters. But at the same time he can't keep his feelings in check. Soon you'll be experiencing a plot where the characters constantly make stupid decisions based on human emotions, impulse and more often face the consequences. There are genuine moments of human connections throughout the plot. It also shows how powerful human emotions can be. It's a constant roller coaster of emotions. There are flaws and issues, like most series, but they are easy to ignore.
