The key feature is likely the LitRPG system. This usually means there are levels, stats, and skills for the characters. Also, the 'monster girl' aspect is important. It might involve taming or interacting with female monsters in some way.
The farm girl herself is the central character, of course. She's usually strong - willed, hard - working, and has a deep connection to the land. There's often a love interest, who could be a neighboring farmer, a city boy who visits the farm, or someone she meets at a local fair. Her family members also play important roles, like her parents who pass on farming knowledge and values, and her siblings who might have different outlooks on life on the farm.
I'm not sure specifically as there could be many novels with such a title. It might be about a girl living on a farm who experiences various lucky events, like finding a rare animal that brings good fortune to the farm, or perhaps she discovers a hidden treasure on the farmland.
Hard work is a very common theme. Farm girls often have to put in long hours taking care of animals, planting and harvesting crops. Another theme is the connection with nature. They understand the cycles of nature and how to work with it rather than against it.
Yes, there are some movies that feature stories about farm girls. For example, 'Country Strong' which has elements related to the life and struggles of a female singer from a rural background. It shows her journey in the music industry and her personal relationships.
The story of a man who transmigrated to a world full of elves and managed a ranch was a novel about a man who transmigrated to a world full of elves. The main character, Chen Li, died in his previous life because of working overtime. However, in this world, he decided to refuse the job at 996 and return to the ranch his grandfather left him. He also gained the ability to make magical dishes. This was a heartwarming story. There were no brainless battles, only farming and a warm daily life. This novel was not related to Pokémon, but an original world.
A little farm girl often helps with milking the cows. She has to be gentle and patient while doing this important job. It's a skill she learns from her parents or older siblings.
One popular theme is the farm girl's journey of self - discovery. She might start to realize her dreams beyond the farm, like going to the city to study or pursue a career. Another theme could be her relationship with the local community. For example, she could be involved in saving the local farm from a big corporation. Also, love stories are common, like falling in love with a traveler who passes through the farm.
Since I haven't read the novel, I can't be certain. But it's likely that the main character is the lucky farm girl herself. There might also be her family members like her parents or siblings who play important roles in her life on the farm.
