Kawaguchi Haruna and Hayashi Kento will be appearing in the new movie "Niigakute Amai" (Bittersweet) which will be shown in cinemas from 10 September. The movie which is based on the same-titled online comic by Kobayashi Yumio that was serialised since 2009 and ended its run in May this year, features Kawaguchi as the heroine Eda Maki who is a pretty and capable career woman but leads an irregular lifestyle. In order to put up a pretense in front of her juniors at the workplace, she pretends that she has a wonderful boyfriend even though she is single. One day, she meets a handsome art teacher Katayama Nagisa and is attracted to him. While searching for a new boyfriend and someone to live with, she ends up living at Nagisa's apartment but discovers to her disappointment that he is actually gay and has no interest in her.
Kawaguchi commented that the setting of the story is very unusual but to be able to eat delicious food and have someone listen to your daily grumbles about work is something very appealing to people who hate being alone or are afraid of loneliness. In the movie, Maki doesn't know how to cook and hates vegetables but while living with Nagisa who is a vegetarian, she starts to discover the power of good food in healing her emotions so the array of cuisine featured in the movie is also something to look forward to.
Kawaguchi revealed that the cooking scenes were all done by Hayashi himself with no stand-ins. Hayashi practised a lot before the filming and all the hand close-up shots were even done personally even though the viewers may wonder otherwise. Especially having seen the bandage on his finger after being injured during the filming, Kawaguchi was impressed with how much effort he had put in and how serious he was about his acting so she had learnt a lot from him as a result.
