"Jeremy was once a successful man with a promising career, a lovely girlfriend, friends galore, and everything that he could ever desire in the world. So, how did he become a useless NEET, nearly overnight?" That is the question his sister posed in her genetic engineering thesis as she has been working on a cure to rehabilitate her suicidal brother back into society. The only catch: he will have to restart his entire life from middle school, now living as her 13-year-old little sister. Will Jeremy embrace his new life as his sister's younger sister; or will he return back to the useless life of a NEET? GENDERBENDER STORY Based Off The Manga: Onii-chan wa Oshimai. I highly recommended reading and purchasing the manga to support the artist and upcoming Anime (2023).
