Synopsis: The Boundary of Delusion

Mok-yeon is approached with a proposition for a threesome by his friend and sexual partner, Sun-hwa. The third participant is Nan-jo, a man whom Sun-hwa has been pursuing. Although Nan-jo is enjoyable to be around due to his wealth and kindness, he lacks excitement in bed. Initially, Mok-yeon was merely curious about Nan-jo, but during the threesome, he found himself unable to look away from him. Mok-yeon then makes an enticing suggestion to Nan-jo, who is determined to protect Sun-hwa from him. "I’d like to have a taste of your body, Nan-jo. Would you be willing to spread your legs for me?"
