The ungrateful villagers force him to return money and petition against him, causing him to lose his government job. Disillusioned, he refuses to help them again. He grows premium melons, becoming the 'Watermelon King' with a flourishing business. Meanwhile, the villagers' watermelons rot, and they weep with regret.
