Due to work, the honest and dull college student Suwa Hinata (played by Shunsuke Daito) met the dignified and beautiful Shirasaki Junko (played by Matsumoto Wakana). After a period of dating, the two established a romantic relationship, but what he did not expect was that Junko turned out to be a real rotten girl. Her emotional journey was not smooth due to her identity as a home girl, and for the simple Hinata, the concept of rotten girls was not very clear before, but after dating, she found that the world of rotten girls was so impactful. Hinata and his classmate Seno Koji (played by Furukawa Yudai) were originally good brothers who talked about everything. Junko's danmei orientation made him quite cautious when getting along with his friends. After that, funny and embarrassing things happened one after another. What will be the ending of this heterosexual couple? This film is adapted from the popular online novel by ぺんたぶ.
