In a small town, a boy named Ango was known for his kindness and helping others. One day, he helped an elderly woman cross a river, not knowing she was actually a forest fairy. She blessed him for his good heart. Years later, when a famine struck the town, most people including Ango died. However, a fruit-bearing tree grew by Ango's tomb, with heart-shaped green and yellow fruits that ended the people's hunger. The fruit came to be known as the mango, honoring the boy with the beautiful heart.
