Uryu Kamihate has had a rough start to life, but plans to forget it all by achieving his dream-matriculating into medical school. But when he arrives at his new foster home, a working shrine, his dream of a quiet place to study goes up in smoke. Not only will he be living with the three beautiful, lively Amagami sisters-but he learns that he must marry one of them and take over the shrine!
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?
