My favorite movie

Hi everyone! I am from Russia and I want to talk about my favorite movie.

My favorite movie is Biri Gyaru. This movie really inspires me. After watching it, I want to learn Japanese and go to Japan. This is strange :D

The girl in the movie was very silly, but her mother found a very good teacher for her.

This teacher helped the girl go to the best university in the country.

Whenever I become lazy, I watch this movie.
