Saba Saba Girl(2020)

Watashitte Sabasaba Shiteru kara

"Everyone should just be 'saba saba' like me!" Nami Amihama (age 28) works in the editorial department for a women's fashion magazine. Nami constantly uses being saba saba (aka blunt) as an excuse for her biased assertions and has been ostracized by her coworkers because of it. One day, when Nami was being her usual arrogant self, she is confronted by her antithesis, Mai Honda (age 26). Mai is beautiful and feminine, and Nami can't hide her irritation. The battle between the self-proclaimed saba saba woman vs. the true saba saba woman begins!
