Raised by an English teacher, Dove was exposed to English media from a young age and became fluent in the language; she also became interested in Western culture, especially the United States.

She found herself unchallenged in the mandatory English classes and surrounded by peers who had no interest in the subject. She also discovered that her teachers were dispassionately teaching merely to meet testing standards, counter to the proper intellectual development of the students. This led her to become disillusioned with the Japanese education system.

Dove started learning piano when she was young, and she aspires to be a great pianist and especially composer.
