Here's a trailer, where characters discuss the release:
Hibiscus & Butterfly continues to tell the stories of the customers of a late-night café in alternate, fantasy Seattle, where humans peacefully co-exist alongside orcs, satyrs, cops and merpeople. It's your job as the coffee shop's sole barista to make people drinks, to chat, and to have a generally chill, cosy time.
Like the original, Episode 2 is mostly about those relaxing conversations, with a bunch of returning and a handful of new customers entering your shop. There are also new ingredients (like the titular Hibiscus) and a new system whereby customers will hand in found items and you'll need to return them to their actual owner. Presumably doing so will unlock new conversation options.
There's a Coffee Talk Episode 2 demo available through Steam if you don't want to wait the four weeks until its release.
