can i ask about more hc about mike/hange or maybe nanaba from vegas au?
Of course!! I’m always excited when people show interest in the vegas au.
Since you didn’t have a specific headcanon question, I’ll just answer with everything that pops into my head.
At first they called each other just “Mike” and “Hanji” but that evolved into Hanji calling him “big guy” or “the big guy” and Mike calling them “Zo”
One time Hanji was going through some papers from work, really focused & lost in thought. They walk into their room and slam the door behind themself without realizing Mike had been walking behind them and talking to them. He got a bloody nose.
Hanji got nail polish on Mike’s couch once while they painted their toenails.
