Manga by author Yamauchi Yasunobu - Status ongoing

High-school boys are really simple and curious creatures. They want one and only one thing: girls. But they havent got a clue about them. Male teenagers are dumbfounded by the girls thought process, actions, appearance and everything in between. They spend countless hours amongst themselves discussing and arguing their theories which are usually completely off base. If only they had the courage to ask them instead of screwing around and talking about nonsensical things, they might get somewhere.

This manga is about robbers, thieves and bad people and how they can't do anything because the good people are even worse than them. Who would've thought?
