The Dangers in My Heart (Boku no Kokoro no Yabai Yatsu) is a romantic comedy about a shy boy whose dark thoughts slowly turn into a real bond. Based on Norio Sakurai’s manga, it has two TV seasons and a film. Here is what to know.
What Is the Story About?
Kyotaro Ichikawa is a shy middle school boy who reads a murder encyclopedia and secretly sees himself as the tortured lead of a psychological thriller. He fantasizes about harming his popular classmate, Anna Yamada. But as he gets to know her, those dark thoughts give way to real feelings, and he begins to fall in love.
The Romance at Its Heart
The comedy comes from the gap between Ichikawa’s dramatic inner monologue and his awkward reality, while Yamada teases him for his flustered reactions. Reviewers describe a slow-burn, realistic relationship in a genre full of clichés, which explains why the series built a loyal following by word of mouth.
