I was right when I sensed that this was familiar!
This is an autobiographical work based on the author's life and marriage.
She wrote a webnovel also with the same title called "I Don’t Like The World, I Only Like You"
If anybody wants to read it the webnovel has been completely translated into English (search Novel updates) and it's also not an extremely long read either.
It's basically a collection of little snippets of things that happen with her and her husband.
