Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.
High school student Uehara Hiroya sometimes visits a house in Mizue, where his friends gather. They spend a time as if they were a family. They love young Hiroya very much. Above all, Jinnai Chiho, a cousin of Mizue Ao and Hiroya, took Hiroya wherever he went and made fun of him as "prince and knight." Chiho was as important to Hiroya as to Hiroya as a close friend, and Ao was a love partner who wanted to enrich his heart. However, in the face of Chiho's marriage, despite Hiroya's desire to stay as he is, the end of a close relationship rather than a bloodline was approaching.
