Electric Footsie Mandagi-san's Sister

Sumire's high school years were marked by a strict adherence to societal norms and expectations. As a well-behaved student, she had always been cautious in her interactions with her peers. However, upon entering college, she hoped to break free from her shell and explore her desires. One day, while wearing a jacket with a peculiar smell, she finds herself in a compromising situation with Nihori, who has caught wind of the unusual scent. Seizing the opportunity, Sumire decides to take a bold step forward and pounces on Nihori, but it's not a romantic overture - rather, she uses her feet to initiate contact.
