Have watched the first three episodes of the series
Ani ni Aisaresugite Komattemasu, Have Difficulty to Be Loved Too Much by Older Brother;
that leads up to the film. I think the series is just five episodes...
From left Asuka Kawazu, Ai Moritaka, Tao Tsuchiya, Ito Ono,
Yurano Ochi - and singer Leola (レオら), who has two songs
in the film.
Asuka, Yurano, and Ai
Ai, Yurano, and Asuka
Not many lines for Asuka so far, but the trio (Asuka, Yurano, and Ai)
have a fair amount of screen time.
Good job Asuka!
