For the production of their game's poolside scene, Blessing Software's illustrator Eriri Spencer Sawamura wants Megumi Katou to model in a swimsuit for her sketches of the game's heroine. However, Megumi refuses to wear such attire unless everyone else agrees to do the same. To ensure the development of their game continues smoothly, the team follows her request as they conduct their fruitful research at a luxury hotel.

Saenai Heroine no Sodatekata ♭: Koi to Junjou no Service-kai was included with the first volume of the Saenai Heroine no Sodatekata ♭ Blu-ray and DVD, which was released on July 26, 2017.
