How to become friends with a QR?

Muffin is 2 month old and he's been with me for a couple of weeks. My question is quite simple: how do I become friends with him? He is hand fed and he doesn't seem to be afraid of my hand, but he doesn't like it either. When he is out of the cage he usually climbs on me and bites my clothes. When I try to touch him he makes a kind of farting noise, but doesn't bite me. Still I assume he doesn't like being touched ,so normally I just let him climb on me and bite whatever he wants to bite (He always bites only my clothes and ever me).  I am working, so I can only let him out of the cage before I go to work and after I come home. In between he is left to himself. Usually he cant wait to get out of the cage, but recently he prefers to stay inside even when I open it. It was actually a pretty sudden change. I am getting a feeling we're drifting apart.  I may be paranoid, but here is the weirdest thing in this story. Besides Muffin I used to have two budgies. I bought them on a bird market and never managed to tame them, so they were completely wild. One of them (male) passed away several days ago.  After that the female started to scream a lot during the day. Grieving I guess.  Recently, Muffin started to produce a similar scream. Together they can scream all day long. I even started to get complaints from my neighbors.  Ever since Muffin started to copy the female's scream there was a sudden change in his behavior. Like I said he does not come out of the cage anymore. Sounds crazy, but I get a weird vibe that the female budgie kind of badmouthed me. What should I do to get closer to Muffin? I really want him to think of me as his flock.
