Riina With A One-sided (?) - Crush On Natsuki (Ume Aoki)

A quick, and for once actually seasonally timely, SAD mini-release for Valentines! This is by Ume who does all the super cute and well-written darinatsu we keep on TLing, and I think this is actually a prequel to all of her other stuff? It’s very cute, though, and hey! Actual Valentines release.
