The Dangers in My Heart (2023)

Ichikawa Kyoutarou, a boy barely clinging to the bottom rung of his school's social ladder, secretly believes he's the tortured lead in some psychological thriller. He spends his days dreaming up ways to disrupt his classmates' peaceful lives and pining after Yamada Anna, the class idol. But Kyoutarou's not nearly the troubled teen he pretends to be...and it turns out Anna's a bit odd herself.
