· Don't panic, be smart, don't worry, be comfortable, don't be quiet, be confident: "Let's have fun menstruating!"
Reliable content from a trustworthy "Menstruation Mentor" with proven expertise and a deep understanding of the educational field.

The author, a veteran health teacher with 18 years of experience, encounters high school girls every day, meticulously examining their bodies and minds and striving to meet their needs.
Since 2023, she has been working as a commissioned investigator for the Seoul Metropolitan Office of Education's Sexual Harassment and Sexual Violence Case Resolution Support Team, striving to create a safe school without discrimination.


Before becoming a public health teacher, she worked as a nurse at Gangnam Severance Hospital and the National Cancer Center, and as the first nurse specializing in sexual violence at the Sunflower Children's Center in Korea, she also took the lead in supporting children and adolescents at risk of sexual violence.


Son Jeong-ah, a trustworthy 'menstruation mentor' who, while working as a health teacher, came to understand how much menstruation affects children's daily lives.
His solid knowledge in the medical field and his experiences both inside and outside the classroom are reflected throughout the book, conveying a warm gaze and affectionate advice to children with sincerity.

· 25 'life-related' questions and clear answers that gather children's 'real' curiosity.

《It's the First Time》 contains 25 key questions carefully selected based on the voices of students heard directly from educational settings.
It candidly addresses the honest concerns, misunderstandings, and anxieties of children who say, "I thought I was the only one curious!" or "Can I even ask about this?", and deals with "life-related" topics that are often overlooked in textbooks or general sex education books.

The author (aka "Health Teacher") provides clear and honest solutions to frequently asked questions from students, such as, "What is menstruation?", "Isn't it true that menstruation doesn't make you taller?", "How many sanitary pads do I need a day?", "Isn't menstrual pain medication bad for you?", and "What if I get teased because of my period?", along with specific and easy-to-understand explanations.

The 'Talk Talk Menstruation TALK' corner goes into depth with practical information such as misconceptions about tampons, what to prepare for menstruation, and how to dispose of sanitary pads, helping children who are menstruating to build the strength to take care of their bodies and minds on their own.

A realistic and relatable "Menstruation Guide" filled with fun and friendly characters and illustrations, and featuring a story about "me" and no one else.

Breaking away from sex education books centered on foreign books, this book stands out for its planning that is tailored to the culture, life, and needs of our children.
In particular, it goes beyond simply conveying information or knowledge, and makes adolescent children feel like it is their own story, allowing them to accept bodily changes, including menstruation, without resistance.

The manga, which features three fifth-grade girlfriends, Dodo, Rere, and Mimi, as its main characters, opens each chapter with a humorous episode that accurately reflects reality.
Through this, children can empathize with similar experiences and prepare for situations they have not yet encountered without burden by imagining them in advance.

The structure of the reproductive organs, types of sanitary pads, and even how to wear and dispose of them are shown in pictures accurately and kindly, so that anyone can easily learn.

· A 'Menstruation Guide' for everyone, regardless of age or gender, from elementary school students to teenagers, at home and in the classroom.

This book is a solid 'menstrual guide' not only for parents of adolescent children but also for teachers in charge of sex education.
Realistic and thoughtful answers and advice can naturally open the door to conversation at home and in the classroom.
It goes beyond simply explaining the changes that come to the body and mind, but also connects to gender equality education, and fosters an attitude of understanding and respect for the other sex in boys who are unaware or have misconceptions about menstruation.

“While preparing this book, I hoped it would be helpful to parents and teachers as well.

I especially recommend that male friends who are going through secondary sexual characteristics around the same time read this book.

“Because knowing about the other sex is the first step to understanding and caring for each other.”
_From the introductory remarks

As the need for menstruation education grows, "Menstruation is the First Encounter" will be a guide for anyone, regardless of age or gender, to comfortably read and relate to, and to create a healthy culture of gender equality together.
