I love that the heroine is a 4-5 year old girl not yet in kindergarten, but not only that, she's also quite knowledgeable for a girl her age, and hilarious to boot! XD
The cover put me off a bit at first, but as soon as I started reading, I immediately adored the art, along with the female and male lead.
Rino is suuuuuuuuuuuuper cute~! Her reaction to things are actually spot-on and quite funny at that. I found myself laughing at several of her thoughts and actions, as well as agreeing with them, for the most part lol.
And Kazuki is adoable as well, what with his shy nature and awkwardness around others, mainly females. It helps that he's a hunk too lol.
As strange as the premise sounds, I find it to be a rather refreshing and great read so far. If you want a cute shoujo with an adorable heroine and equally adorable male lead, then this is for you. Don't let the age-gap thing put you off. It's a lot better than it sounds. 😀
