   Summary

   A Collection of Short Romance Stories with Agnes Tachyon and Jungle Pocket, set following the fateful 2001 Japan Cup, and the weeks and months following. I'll add many, many chapters, so just take each one as a small glimpse into a slow-growing relationship of two Umamusume and their journey of self-discovery and emotional bonding.
