隣の席の間宮さん
Mamiya is a quiet and reserved high school girl who sits next to the protagonist in class. She is known for her large chest, which often draws unwanted attention from other students. The protagonist, an ordinary student, tries to focus on his studies and daily routine, but Mamiya's presence becomes increasingly distracting. Despite her shy demeanor, she seems aware of the effect she has on him.
One day, Mamiya decides to show off her breasts to the protagonist, breaking the usual silence between them. This unexpected act leads to a series of intimate encounters in the classroom and other private spaces. As their relationship deepens, they explore their desires and boundaries, moving from awkward tension to mutual attraction. The story follows their secret interactions and the growing connection between two classmates who discover a hidden passion beyond their ordinary school life.
