I think kurumi just misunderstood the "LOVE" that she has on her step-sister Sena. I am satisfied how it ends but I want to see more development to those four. I had this feeling that Kurumi has this more deeper meaning of love to Yasumi that might she realize through if there were next episodes. Hahaha... What I am thinking of. Yet ofcourse I like Sena x Yasumi in the end. ehehe
