Why hasn't After The Rain With You been officially translated yet?

It's a cute anniversary story based on Nemona and the female player character growing close, and it's the basis of the Biri-Biri music video (which DID get an official translation). So why haven't we seen this in English or any other non-Japanese language yet? I'd be willing to pay for a copy if they put it on the official store.
