On that day's filming, there was an intimate scene when Amami had to take the initiative to pounce onto Abe. Amami praised her co-star for being able to withstand her weight (she is 1.71m tall) using his stomach muscles and that he's very dependable due to his big build (he is 1.89m tall). Abe commented that working on this film felt as if he was in an action film because there were scenes when he had to be subjected to "physical abuse" such as forced to turn his neck many times. Yukawa praised his lead actors for making the story more believable and that they are at the right age now to show the reality facing the couple in the movie.
