Your average, late '80s to early '90s feel, superficial, "pure love" shoujo manga. But not a bad little story for having only 7 chapters. Basically, girl meets boy. Boy turns into young adult at night. Girl meets young adult upon waking in the morning. Boy and Girl are related to Frog Prince FairyTale. The princess' kiss saves the prince from his curse and they (all?) lived happily ever after. The End.
A good story, I slightly felt like there could've been more to it. Especially with her loneliness and more character development with her mother. It just seemed that some parts were cut short. I liked the story and I was happy for the ending with them together though.
