The challenging newlywed life of an otaku wife! Ayami Kazama, who grew up going to all-girls schools with a 2-dimensional view of love, never had a boyfriend until she was 30, but she was able to get married without incident. She thought she had finally graduated from her 2-D world, but she didn't account for the fact that her husband is a manga artist, too!
