World of Delight (レインツリーの国, Reintsurī no Kuni, Raintree Country) is a 2015 Japanese youth romance film directed by Yoshishige Miyake.

[3] This work is a love story between the main charactor, who is a normal hearing person, and the heroine who is the late-deafened.

Seeing Tamamori like this, co-star Kataoka Ainosuke VI gave him advice as a Kansai region person.

Kataoka said, "Tamamori-kun was a really nice young man and eager to learn," and added, "I want you to become a member of the Kansai people (laughs)".

In Hitomi's house, the direction and arrangement of the furniture were considered after talking to an actual hearing-impaired person.

Curious about the contents of the second volume, I searched the Internet and found the website "Raintree Country," of which Hitomi is the administrator.
