The ending of "Hyouka" is that Houtaro agreed to Chitanda's request and temporarily played the role of holding an umbrella for Chitanda, who helped the queen's baby during the baby birth festival. Chitanda Eru and Oreki Houtaro each found their dreams for the future, and they also understood their feelings for each other, but they did not express it clearly.

The TV animation "Hyouka" is adapted from the "Classic Series" novel originally written by Japanese mystery novelist Yonezawa Honobu, and is titled "Hyouka", the first part of the series. It tells the story of Oreki Houtaro, a high school student whose motto is energy conservation. For a small reason, he joined the Classical Literature Club, which is on the verge of being abandoned. The members of the Classical Literature Club include the heroine Chitanda Eru, as well as Mayaka Ihara and Satoshi Fukube who he has known since junior high school. This is a youth school mystery drama in which the four of them use Kamiyama High School as the stage to reason about one incident after another. ?

The male protagonist Oreki Houtaro is an energy conservationist, that is, he does not do anything unnecessary because he does not want to regret it. Some people say that he is alienated and world-weary. In this way, he entered the Classical Literature Department because of his sister's order. Although he finally recruited four new members, he was involved in the mystery of the president who suddenly dropped out of school thirty-three years ago. The president left behind a magazine named Bingguo.
