Should I get another budgie and how do I introduce them?

I asked this question yesterday and got two helpful answers, but I am looking for as many answers I can get on this question. Thanks!

I got my first ever budgie, Tiki nine days ago. I can hold millet and he will eat it and I can also pet him. That is it though. He won't step up onto my finger, and I don't think he wants to. I know that he is still new and I need to work with him, but for now I really think he doesn't want me to play with him. He usually just sits in one spot and only moves around a little. He isn't completely still but he doesn't like to fly all around or play with his toys. He also chirps rarely. Except for when I watch a YouTube video with budgies in it, then he chirps like crazy. It makes me sad because he thinks there are other budgies, when there aren't. I think he gets lonely. I would really love to bond with him, and I'm pretty sure that if I get another budgie he won't want to bond with me. But on the other hand, of course I want him to be happy. I think he will be happier with another bird to play with. I want to get another male because I heard they get along the best. Also I am going into ninth grade so Monday-Friday I will be gone for six hours. I think he will get lonely and bored without me for six hours. I think a budgie friend would be good for him, even if it means he won't want to bind with me. I also have questions on how exactly I introduce them. Please help! :)
