No news about a sequel, but I assume you're talking about the fandisc Hiyoku Renri no Darling? Well if you heard about Chaos;Head's fandisc Love Chu☆Chu! (which didn't get an adaptation) it's practically just taking out all the horror/suspense in the story and just making it a lovey dovey get with your favorite girl story. So nothing really special to tell there
but no sequels here.
