weird coincidences in writing

I just realized I named Seishiro's sons like the surviving Sakhalin huskies in the Japanese antarctic expedition of 1957, depicted in Nankyoku Tairiku, a series not even aired when I decided on the names.

However, considering his choice of "Pochi" as Subaru's nickname in phone chat, it's an oddly fitting coincidence, don't you think? :-D
