#mulmangcho

There is a very common idea in the fanbase that all 3 of the mice are related-this is due to them referring to eachother as brother in the English and Russian subtitles.

But what about the original Korean? If we look at that, Oegwipali refers to Mulmangcho with the following-by "hyung-i" or 형

Hyung is a very complex word in the Korean language-but to put it simply, it can be used by any younger male referring to an older male in a respectful way or a younger male friend to a older male friend. Even couples use it for eachother! This can translate as "brother" but does NOT always make characters siblings...for example, There's another notable use of the word "hyung" in Squirrel and Hedgehog.

With Undochi and Geumsaegi! Undochi calls him "hyung" in a respectful way, and they obviously aren't related. So why does Oegwipali call Mulmangcho the word hyung?

It can be for many reasons-perhaps Oegwipali just respects Mulmangcho, and calls him as such due to him being older. Perhaps they feel a sense of comradery after the Battle of Mt. Rock (notably he didn't call him hyung until after that) perhaps it's just due to their closeness-sometimes they act just as close as Juldarami and Geumsaegi! Overrall, there are many layers to this and I don't think they should be called siblings just because of a honorific that's often used between people who ARE NOT related. Some people ship the two-and may not consider them to be brothers. For example, some South Korean analysis of SaH simply calls Oegwipali his subordinate.
