The Case of the Missed Fish Being Big, But the Caught Fish Being Too Big

The youngest daughter of a ducal family renowned for martial arts, Maria (nicknamed Mimi), was recognized for her talent in martial arts and raised as the heir (as there were only daughters). However, when a long-awaited younger brother was born, she had to step down as heir. Since the noble sons of her own country were already engaged, she sought help from her best friend Aida in the neighboring country, studied abroad, and started her quest for a partner. Renato, the first prince of the neighboring country, was engaged to Aida. However, knowing that Renato's younger brother, the second prince Plachido, liked Aida, he declared the engagement broken to Aida to support his brother's love... or so he intended. But Renato, who had poor eyesight, mistakenly and loudly declared the engagement broken to Mimi, whom he met for the first time (lol). They had the worst possible first encounter, but Renato was drawn to Mimi's overwhelming martial prowess and purity, and Mimi gradually fell in love with Renato. It's a Cinderella story. Every time she faced a pinch, it was fun how Mimi, who should have been a princess, solved it with overwhelming strength (with her fists). It's also fun how the entire royal family grew to like her strength. Mimi is really strong! (lol) It was an enjoyable anime that could be watched at a brisk pace! I've only watched up to episode 8 so far, but I hope Mimi can end up free and happy like this.
