Taira plays the role of Oriyama Karin who is an innocent girl from a rich family and in the first year of senior high school. On her 16th birthday, the birthday present given by her parents is a marriage partner Tsurugi Nao (Nakajima), a third-year student in the same school who also happens to be her first love and the most popular guy in school. However, Nao's intention is for the Oriyama family's fortune thus Karin is stuck in a one-sided love marriage. Just then, Ebina Izuzu (Chinen), a first-year student who is a rich guy and in love with Karin, comes to know about her secret marriage to Nao and presses the latter to divorce Karin.
Nakajima commented on his character that Nao is a guy with two clear different faces where he treats Karin coldly but can sometimes be gentle and warm towards her so he hopes to be able to show this difference in his acting. As for working with Chinen, he said that it had been 9 years since they worked together in the 2008 drama "Scrap Teacher ~ Kyoushi Saisei ~" so he's very excited about being rivals with Chinen this time in the movie. On the other hand, Chinen said that since they last worked together when they were both in junior high, he is also looking forward to playing rivals with Nakajima now that they are adults. With regard to working to Taira, they only acted together for one day in the movie "Shinobi no Kuni" so they will have more time to interact with each other this time and he hopes that their acting will be able to make the viewers feel tingly.
Taira commented that this will be the first time that she will be wearing a wedding dress in a movie and she never expected herself to be doing that at the age of 18. As such, when she was doing the costume meeting which coincided with her elder sister Airi's own wedding, she couldn't help but imagine how her future wedding will be like. As for being in a love triangle with two vastly different guys, Taira said that this is precisely what's interesting about the story and can't wait for the filming to start.
