The series follows a group of young people and their struggles with love, and it's divided in three parts. The first part tells the story of Jae-min (Ryu Ui-hyun), a student addicted to masturbation and accepts the "Stop Masturbation in a 100 Days Challenge" in order to confess to the girl he likes, Ye-kyung (Cho Mi-yeon). The second part tells the story of Yu-ra (Jo Yoo-jung), a wannabe girl crush who in reality is a naive, delicate, religious girl, whose boyfriend leaves her because she is too "conservative". A change comes when to save face, she convinces acquaintance Nam-ho (Ryeoun) to pretend to date her; she believes she has no interest in him, but to her surprise, she begins to be drawn to his wild and edgy nature. The third and last part is the story of the mysterious J, who appeared in front of Na-eun (Kwon Young-eun), an overweight girl who has never received anyone's attention, and thus decides to find J's identity.
