"Heart Cocktail Colorful is based on Seizou Watase's Heart Cocktail manga, which Watase wrote in the 1980s and has 11 volumes. The full color manga told love stories set in urban environments. The new manga will continue to tell love stories, but will take place in the present day. Some of the stories will include a love story with an age difference, a love story between two people who cannot meet due to the pandemic, and the love of a single mother."
