This show is about Pucca and Garu, who are about twelve years old. The entire show, Pucca harasses Garu and tries to forcefully kiss him against his will. She continually tries to force him to fall in love with her, even creating a love potion on at least one occassion to force this affection. This is not "a crush" or "head over heels in love," this is Pucca being completely and unhealthily obsessed with Garu and harassing him. She is, effectively, Garu's stalker.
What sort of moral is there to this story? Not only does Pucca stalk Garu, she is REWARDED with "Pucca power" for every kiss she steals from him.
This show pushes the idea that if you like someone and they don't return the feeling, you should force them love you and kiss them without consent. Stalking is not something we want to encourage.
It's especially concerning to me that the characters are children, meaning this show is likely aimed towards kids. What is this teaching kids? It's teaching that "no" means "try harder." That is unhealthy. I am very glad this show was discontinued.
