Searching for My Mother in Another World

Transported to another world with my whole house and my beloved dog?! A heartwarming x slow life story in a new land begins! Right after graduating from high school, I, Hatano Sui, lost my father, the only family I had. Among his belongings, I found a deed to a secluded house deep in the mountains. When I went to check it out, I was transferred to another world, along with the entire house and my dog?! We were immediately attacked by monsters, but my dog started to display mysterious powers, and somehow, I felt like I was getting stronger too. While still trying to figure out things, a beautiful elf girl rushes to our house and claims to be my childhood friend. My dog seems to like her, so she might be telling the truth. On top of that, it seems my mother, who I was told had gone missing, is alive and well in this other world...?
