“How does the fact that my favorite boy doesn't eat meat affect me?”

This book is mainly about Yoo-jin's exciting love story. The reason why Yoo-jin started eating less meat was that she wanted to see her crush boy eating every day and didn't want to leave him alone. This simple reason naturally evokes the reader's empathy more than any knowledge or logic. It's natural to become more curious and want to get closer to someone when you like them. However, the more you learn about Choi Hee-won, the wider Yoo-jin's world becomes, not narrower.

After learning why her favorite boy doesn't eat school lunch, Yoo-jin looks back on the daily routines she has taken for granted and discovers various options that have always been there but have been ignored. And Yoo-jin has friends who share her trials and errors, such as leaving school, rescuing stray cats, or eating less meat. This book is not a novel that recommends “vegetarianism.” It is said that when a hundred people make a hundred choices, each of those choices has a different reason. So, this book tells us that let's value our own choices, not anyone else's, especially when it comes to what we eat, whom we like, and what books or music we like. This book will also bring back the various colors of life that may seem faded to teenagers who feel pressured to find the right answers in school, entrance exams, and many assignments and competitions.
