Opening the Door to Hinata-san's Heart

日向さん、星野です。

Misaki Hoshino is a first-year high school student known as the most reliable guy in his class. About a month after school starts, a teacher asks him to deliver handouts to his classmate Momo Hinata, who never attends school. When he arrives at her house, he discovers that Momo has been a shut-in for the past three years, never stepping outside.

Despite not even knowing each other's faces, Hoshino begins visiting Momo regularly, communicating with her through her bedroom door. As their after-school conversations develop, Momo's feelings slowly emerge, trapped behind the door. Hoshino's ordinary days start to change as he becomes part of her world, and together they navigate the challenges of her isolation and the budding romance that grows between them.
