Pixiv, where it gained a wider readership and popularity. Although there are a couple of sexual interludes in the latter pages of the story, what it mostly entails are the ruminations and observations of a 28-year-old woman on her life and circumstances. Kabi struggles with finding herself, both in terms of her family and friends. She seeks the acceptance of her parents, though feels she falls way short of their expectations. She bounces from job to job, seeking friendship and social capital, though not really finding either.
This book's creator Nagata Kabi is fairly new to the comics world, and she apparently has another manga she is working on called Solo Exchange Diary. She talks about her works and career in this interview.
All of the reviews I have read about this book have been full of praise. Shea and Derek from The Comics Alternative called it the apparent "manga of the year" and added, "This is a manga all about self-discovery, a diary-like account of the
author’s attempts to understand herself within the context of her
culture and her yearning for what she calls 'next level communication.'" Kat Overland called it "a wild ride from start to finish." Aria wrote, "I wasn’t expecting to be blown away by this – but I was."
My Lesbian Experience With Loneliness was published by Seven Seas Entertainment, LLC, and they have more information about it here. As should be clear by now, this book is intended for mature readers.
