Nezu-san no Ongaeshi

"I want to be able to talk to other people." Shoko Komiya is an office lady with a communication disorder. One morning at the train station, she accidentally drops a big box of candy. That was when Nezu-san, a very hungry hamster, suddenly appears. He puts one of the scattered candies in his mouth and says, "In return, I will grant you a wish." (Source: Comic Brise, translated)
