A few soybeans, three parts destiny, seven parts hard work. A female college student majoring in food science time-travels into a destitute peasant girl. With bare walls at home, a lazy older brother, and a dying father leaving behind only three soybeans, she refuses to yield to fate. Growing bean sprouts, making tofu, grinding soy milk, and brewing soy sauce, she goes from a small village stall all the way to becoming the richest person in the country. Some laugh at her, saying, "A tofu vendor has no right to talk about ideals," and she laughs back, "You sure enjoyed eating that tofu when the time came." This time, she will make her whole family stand tall and let the whole world know that even though a bean is small, it can blow up the world.
