While the perfect getaway for most girls her age might be a fancy vacation with their loved ones, Rin Shima's ideal way of spending her days off is camping alone at the base of Mount Fuji. From pitching her tent to gathering firewood, she has always done everything by herself, and has no plans of leaving her little solitary world.

However, what starts off as one of Rin's usual camping sessions somehow ends up as a surprise get-together for two when the lost Nadeshiko Kagamihara is forced to take refuge at her campsite. And even after Nadeshiko's sister finally picks her up later that night, both girls silently ponder the possibility of another camping trip together.

这也是，某个冬日的故事。山梨的女高中生志摩凛，乘着钟爱的机车一路前往滨名湖。从除夕这天开始，久违了的单人露营。从山梨出发前往静冈县磐田。在磐田迎来新年，今天则是第三天。虽然行驶了相当长的距离，但仍然感觉很开心。就在此时，停靠在海边的凛忽然想道「果然，我还是很喜欢单人露营啊」
另一方面，了解凛这份心情的抚子，也产生了新的想法。喜欢和大家一起露营。做完饭后满足地享受也令人开心。但是「我也很想像小凛那样，试试看单人露营啊」
抚子与凛，从这两人的相遇开始的户外系girls story第二幕，现在开幕。
