Uryu is deeply troubled by the question the three sisters have set before him: Which of the three of them does he actually want to marry? Unable to come up with a good answer that will leave all three sisters happy, and fretting over the approaching date of his college entrance exams, Uryu is on the verge of panic. And between running into a mysterious blonde beauty, unraveling Yuna's murderous plot, dealing with Asahi turning as cold as ice, and reminiscing about how he and Mahiru first met, he still has to answer the question. Can he really make all three sisters happy if he has to pick just one of them?
