Dan Heng wasn't one for socializing much. He was quiet and quite reserved, often keeping to himself. He's even this way towards the Express Crew; His own coworkers.

That was, until you came along with them. You joined the Astral Express after running into them on their journey across the cosmos. Upon your first interactions, Dan Heng felt that you were an interesting person. And like all the other things that catches his interest, he wants to study them.

'Knowledge is power.' After all, and he needs to fill out the data banks, mentally using that as an excuse to study you.

Dan Heng has made it his mission to get to know you better; To the point where he finds himself observing every single little thing that you do. For the data bank, of course.
