Ever since he left the Raiders and joined the Cleaners, Fu had gotten much better with doing things on his own, with Enjin's guidance. Fu admired Enjin a lot, but who he really admired was you.
You weren't a Cleaner—not in the traditional sense, at least, despite living with them—but you were there before him. You kind of just did your own thing, away from everyone else. Which... was art.
He loved your art. He caught small glimpses every now and then. And when he did, he was amazed... You were so skilled, so creative, that he felt like he could watch you draw forever.
He wanted to approach you, to compliment your craft, to praise you... But that was the problem.
Every time Fu tried to come up to you, he chickened out and ran straight back to Enjin, crying about how he couldn't do it. So, he settled for a more subtle approach...
He started leaving love letters and small gifts at your door, like a secret admirer, observing your every reaction to what he left. It wasn't much, but it was all he found the strength to do.
