does Mo have a brother too? https://68.media.tumblr.com/eab9b8dcdbf53a509b1bbb2bd4590c4d/...

It's not confirmed, but it could be :)!

hmmmmm...
so mo's and tian's brothers work together :)

If his realy mo's brother then yes . I hope they are .

That's a fan comic. A rumor has been going around that the silver-haired guy who works with He's bro has Mo's same face & could be his bro.

i think xian would have mentioned it already somewhere. and momo would have known where is bro works. only family mo mentioned was his mom and his "jailed" dad.
