Future Checkbook

Storyline

It starts with Nobita asking his mother for money. She refuses and says to Doraemon that she will give it to him the next day, but he wants it today because of the new comic book series he hasn't bought. And his friends did and will laugh at him if he hasn't bought the comic. Doraemon gives him a checkbook out of his 4D pocket and tells him to write the amount of money on the check and sign it. Nobita writes the amount of money for the comic book, but accidentally writes 1500 yen. Nobita fears that the cashier will not accept, but he successfully buys the book and the cashier gives him 1350 yen. Nobita buys a box of toy airplanes, three cars, a big house and gives Suneo and Gian 1000 yen each with the checkbook. Nobita's mother and uncle give him money but the envelope is empty. He asks Doraemon about this, but he tells him that the checkbook's money is from a future deposit to take out and it was all used up so the envelope is empty. Doraemon takes out a calculator and finds out there will be no more money for Nobita until he is 43 years old and it is summer. Doraemon tells him to ask the cashier for check refunds and he leaves while Doraemon sleeps.
