Synopsis
Nogizaka Haruka no Himitsu revolves around the seemingly perfect Haruka Nogizaka, a popular and admired student at Hakujo Academy.
Haruka harbors a secret hobby that clashes with her refined image: she's a passionate otaku.
Her secret is accidentally discovered by the ordinary Yuuto Ayase.
Instead of exposing her, Yuuto promises to keep Haruka's otaku nature hidden, leading to an unlikely friendship between the two.
The series explores their evolving relationship and the challenges they face as they navigate the social complexities of the school, especially considering Haruka's celebrity status and their growing closeness.
Expect lighthearted moments as they try to protect Haruka's secret while dealing with the ever-present school gossip and misunderstandings.
