The main character who wants to have a bicycle changes all the calendars and clocks in the house to deceive his father.
That’s how he gets his allowance, but he tells everyone he’s been tricked into coming to work, and everyone believes it’s the first day. The main character goes to buy a bike, but the sale is over and the store owner thinks today is the first day after watching the news, so the sale is over. I think the main character told his lie to his father and the movie ended.
Maybe it’s not the first day. But because of the movie, I skipped a day and tried to get pocket money in advance.
