Regarding the perpetual daily calendar project for Kotoba no Ha, we're making a major change!
Initially, the plan was to collect postcards with illustrations and make a daily calendar,
but it seems unlikely we'll receive enough handwritten submissions within the submission period, so we've decided to make it print-only.
Therefore, since we're going to make it print-only anyway, we'll commission a company to create it for us.
