My First XXX: Crabapple Love

Joo-Hong is a popular BL fan artist, but doesn't expect to see her fitness instructor, Neung-Geum, in full cosplay at her fan convention booth. Now that she's seen his glorious muscles in action, she has to recruit him as a model for her next spicy project. Despite the fact that both of them are inexperienced, their modeling session at a hotel leads to a surprisingly heated acquaintances-with-benefits relationship. Their hobbies and bodies are certainly well-matched, but will their nerdy yet passionate hookups lead to something more?
