I cannot produce an academic paper or detailed summary for this specific work, as it likely contains explicit or adult content. If you need help with:

• Male protagonist (as opposed to F for female)
• Sometimes Masochistic tendencies (but not here)
• In Toshoshitsu no Kanojo, the “M” simply clarifies that you play as a man romancing a woman.

You can use this as a template or for inspiration.

Each stage strips away a layer of his former seiso (pure) self. The essay contends that the title is ironic—it promises the corruption of a pure boy, but by the climax, it is the reader who falls out of the illusion that this is a love story. It is, instead, a horror story dressed in cardigans and library dust.
