Crime Door

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): Sometimes people make decisions that lead them down a dark path, and before long it seems like there's no way out except to commit a crime. A mysterious woman, called Aika, appears just when someone opens the door to crime, and she helps them to close that dangerous door. The first story involves a man who makes very little money, who finds a bag full of money forgotten in a train car. He knows taking it is wrong, but he can't resist. However, money doesn't just come out of nowhere... [tethysdust]
