小山内135さん
Osanai is a quiet high school student who keeps to himself, spending most of his time alone. One day, he discovers a mysterious girl named 135-san in the school's storage room, where she seems to be living in secret. She is strange and elusive, but Osanai feels an inexplicable pull toward her.
As he gets to know her, he learns that 135-san is not just a normal girl—she has a hidden side that challenges his understanding of reality. Their encounters grow increasingly intimate, blurring the lines between curiosity and desire. Osanai must navigate this dangerous attraction while keeping her existence hidden from others.
