>>2240753Why is it so difficult to understand that he had feelings for Kuroneko that are lesser than his love for Kirino?
>or he just realized his love for his sister just at the end?Him learning to accept his romantic feelings for his sister was kind of the point. He comes to accept it while Kirino is helping him deal with the break up, and acknowledges that his feelings for Kirino were romantic from the start, and "because we're siblings" was an excuse.
