The moment my engagement with my human trash fiancé was annulled, memories from my past life returned. I was formerly a hardworking agriculture researcher and a woman who went to farming college! After getting chased out of my family, I decided to stick to my strengths and live a worry-free and comfortable life while farming, but... "That's my sword." "No, it's my hoe?" "It's my sword!" "I told you, it's my hoe!" Suddenly, a beautiful blond man—who looked perfectly fine on the outside—appeared to take the hoe I picked up from the ground away from me! This is the start of a farming romance where we'll meet our loved ones as well as pick mulberries (kill two birds with one stone)~
