Nagi Shinonome, known as the "Ice Princess," is a beautiful girl with a cold attitude who does not get along with other people. One day, Souta Minoru notices her being molested on the train and musters up the courage to step in and save her. The next day she comes up to him again and asks him... "I want you to stay by my side." Can Souta continue to be "just friends" with the "Ice Princess," who melts sweetly only for him? (Source: Kadokawa, translated)
