This is basically a yuri doujin featuring the non-transformed characters from HeartCatch Precure. Although heartcatch characters appear, the main characters in this doujin are Tsubomi (Cure Blossom) Itsuki (Cure Sunshine). Since they don't do their thing while transformed, their Cure names are not tagged.
This is version 2 of the scanlated doujin which includes corrections and re-edits.
