I fucked up and took too long to write my Pomu farewell letter and there's basically no chance it'll make it in before the deadline if I mail it myself. Any advice? Been trying to find someone in Japan who could print my letter and mail it domestically, but if there's anything else I should consider, I'd love to know.
This will likely be my final positive interaction with Nijisanji, so I'd like to be able to pull it off.
