Nana to Kaoru

Seventeen-year-old Kaoru is a virgin with an S&M fetish, quietly nursing a long-held desire to share that side of himself with Nana, his childhood friend. Nana is seen as flawless and constantly draws attention from the boys around her, while Kaoru’s laid-back attitude toward school has helped push the two further apart over the years.

A sudden mix-up changes their dynamic when Kaoru’s mother asks Nana to hold onto some of his S&M items. Nana ends up trying on a leather one-piece Kaoru bought, only to get stuck inside it without the key. After Kaoru helps her out, Nana finds herself more curious about his hobby than she expected, and the pair begin meeting for “breathers”—private sessions meant to ease the pressure Nana feels from maintaining perfect grades and an impeccable reputation.
