Yama, Kaimashita: Isekai Kurashi mo Warukunai

Synopsis

I'm Satsuki Mochizuki, 27 years old. After being unexpectedly dumped by my boyfriend, whom I thought I would marry, I tried solo camping and surprisingly found it quite enjoyable. In a twist of fate, I end up buying a mountain, only to discover it's an unexpected fantasy world. Now, I aim to escape from tent life and embark on a slow life in this otherworldly existence, prioritizing a tranquil lifestyle over romance. (Source: Kakuyomu, translated)
