How Long Is “ももいろそらを”?

High school student Izumi Kawashima, whose daily routine is rating newspaper articles, finds a wallet containing a large sum of cash. Instead of returning the wallet to its owner, Izumi decides to lend a substantial portion of the money to a middle-aged male acquaintance. She eventually returns the wallet to its owner, a wealthy high-school boy named Koki, who notices the missing money, and as compensation, asks Izumi to do something for his friend - to create a newspaper that brings happiness to its reader.
