Naya once had an older brother named Naru, who died by suicide after suffering from toxic masculinity and relentless bullying at school. Years after his death, Naya graduates from middle school and decides to attend the same high school her brother once went to. But unexpectedly, she ends up in the same school—and even the same grade—as Dira, the younger sibling of the student who used to bully her brother. From there, tension rises, and conflicts between Naya and Dira begin to unfold.
