Haikyu!! dj - Unmei (fate)
A short prequel to Haikyuu! where Hinata and Kageyama once meet in a garden over a cat. Very simple art and story, but cute!
Aka To Kuro (katsura Komachi)
The prequel to Rouge and deals with why Ai is so indebted to Yamato. It explores his abuse a bit more and Yamato's kindness to him. (When Nagato showed up toward the end, I screamed.) It's also the romance between Yamato and Yukio.
Memory of the Future
Tsumasaki ni Kiss
Prequel to Gravity Eyes Long-time lovers and heirs to rival yakuza groups hit rough waters when one agrees to marriage and the other is pursued by the puppy-like host Kyoya (who will get his own happy ending in Gravity Eyes). Injured over his lover's seeming infidelity, Homura temporarily dates the sweetly persistent Kyoya -- something that set the comments section aflame. I thought it was a totally reasonable move by someone who is heartbroken and devastated, but then I've been heartbroken and devastated. If I'd read this while younger, I might have been mad too.
Itsuka koi ni naru made
The prequel to the one about the couple who takes care of their best friend’s baby. This hit all of the right emotional buttons. I loved it. and we got to see more of the teacher who will eventually be the father of Tomoe’s baby.
Jealousy (Scarlet Beriko)
