I've already written the part where the letter and matchmakers reach the Unclean Realm. So I'm skipping that on here. Meanwhile in Lotus Pier:
It has been long enough since Jiang Cheng sent the letter for the matchmakers to reach Qinghe and be at least partway back to Lotus Pier. He hasn’t received a reply.
He hadn’t necessarily expected Nie Huaisang to write back as soon as he received it. Jiang Cheng realized that the final letter had been somewhat cryptic. But surely, once the matchmakers arrived and it was all clear, Nie Huaisang would have written back to him. Perhaps the letter got lost? Or perhaps Nie Huaisang had taken offense after all. Jiang Cheng hoped that wasn’t the case. Losing Nie Huaisang through this fiasco was the last thing he wanted.
