I'll test whether girls really can't be together." "—What? Whatttt?" From that day on, after school, they would hold hands, gently stroke each other's hair, and eventually even engage in ○○...?! Will Marika still be able to insist that it's "ridiculous" even after 100 days?? A comic rise of a GL love comedy that shines as the number one in the Amazon Kindle Store's light novel category!
