Tofu consistently asks his friend Bill to do his science projects and math homework, offering chocolates and fast food as rewards. Bill, though initially hesitant, agrees due to the incentives.

Bill falls ill and is on sick leave for two weeks, leaving Tofu to face his schoolwork alone. Tofu realizes he doesn't know how to do his math homework and expresses distress.

Miss Ellie, Tofu's teacher, scolds him for not submitting his math workbook and assigns him extra exercises as punishment. Tofu cries, admitting to Tia his reliance on Bill and his inability to do the work himself.

Tia criticizes Tofu for his bad habit of avoiding responsibilities and hard work, explaining that he will never learn if he continues this behavior. She decides to tell him a story.

Tia narrates a story about a kind fisherman named Finn who regularly gives money to a lazy beggar. Finn realizes the beggar is capable of working and decides to teach him a lesson.

Finn invites the beggar to the river and has him cast a fishing net. The beggar is impatient but eventually pulls in a net full of fish. Finn explains that hard work and patience lead to a greater reward than begging.

The beggar thanks Finn for teaching him the important lesson of self-reliance. Tofu, listening to the story, realizes his own laziness has overcome his ability to work hard. Tia affirms his understanding.
