A businessman named Tokuya was stuck in Fukuoka due to his flight being canceled on his return trip. Feeling lost, he met a CA at the lounge who turned out to be his neighbor, Kanon. They hit it off and spent the night together. Unable to find a hotel room, Tokuya stayed over at Kanon's place under her kindness. Their affair continued during trips and airports using the excuse of work-related travel. As their actions escalated, they began exploring sexual acts that Tokuya couldn't do with his wife. This led them to engage in more explicit activities, including live chats featuring young wives and mature women.
