Let's talk about the anime "The World is Still Beautiful"

At the time, the title seemed so long and I had no idea what kind of story it was. I clicked on it out of curiosity, and it turned out to be very sweet. I remember the female lead was the youngest daughter and was somewhat forced into marrying the male lead. Everyone thought the male lead was an old man at first, but unexpectedly, he was a shota. It's a rare older woman/younger man romance. The female lead's family has a superpower to make it rain by singing, and there's even background music when she sings (X) Anyway, her singing was beautiful and moving. The male lead later falls in love with the female lead. (´-ω-｀).. I thought it was too short with only 12 episodes back then, but I've forgotten most of the plot now. It was basically the female lead taking on missions, completing them, and then a bit of sweetness (๑´ㅂ`๑) Overall, it was really good (Highly recommend~!) ୧₍˄·͈༝·͈˄₎୨
