It's a simple, sweet story about a smart, doesn't ever get into trouble girl who has a crush on a tardy, imaginative boy. Characters:- The guy is mostly an air-head and an adventurer. He bunks school and goes wherever he wants without a care in the world. He loves to have fun, basically. The girl secretly likes him and follows him in his adventures reluctantly, as a way of looking out for him. She's a sincere girl for the most part and gets dragged into his easy-going pace. Art:- It's like any other shonen manga and even colored at times. Story:- It's a one-shot but captures the gist of two oppositepersonalities getting to explore each other, even if it's for a very short while, and not something the other wants to get into

It kind of reminds me of Tonari no Seki-Kun. If you liked that, then you can give this a try.
