My brother suggested taking his younger brother and sister-in-law camping in the mountains. The younger couple happily agreed to go to clear their minds, and my brother was very pleased to be out with his younger brother's beautiful wife, Tsumugi Akari (who he has unrequited feelings for). Suddenly, a storm hit, and the small tent couldn't withstand the growing intensity of the storm. The three of them decided to run to seek shelter in an abandoned house, where there was no phone signal to contact anyone for help. It's unfortunate for the younger brother, who was forced by his older brother to go find help in the storm, while the older brother stayed there to take shelter with his sister-in-law. While hurrying to the shelter, both of them got drenched, but there was only one blanket to share. Sitting there alone together, the older brother couldn't help but think that this was his only chance...
