[From ShoujoMagic]:
Tale 1: 3D Material
Suzushiro, a young adult studying design, yearned for variation in her mundane routine. As a result, when Eiichi propositioned her to surrender her virginity, she agreed without reservation. The exchange was straightforward and commitment-free. However, as Eiichi sets his sights on Mizuno, a business major who is more attractive and widely-liked than Suzushiro, she starts to question their relationship.
Tale 2: Angel's Corridor
