You now know that there are benefits, very pleasurable benefits to being under the control of your roommate and friend.

Now comes the time when we find out what he does to you next
Entertain me, Bestie
What do you do when you're bored and your best friend is deeply under your control? You use them to entertain you. You fractionate them, mess with them, have them do all sorts of fun, silly & maybe even erotic acts to entertain you and amuse you. That's what a good friend would do, they'd entertain me.
Not Friends Forever
What's that? you're trying to fight the powers of the bracelet? You're trying to fight my powers and control over you? That's adorable, we'll see about that, give it your best shot but remember that the harder you fight, the deeper you'll fall, and if you fail it'll be over, you won't really have a choice, you'll be my best friend forever and ever and ever
Fractionated Friend
What if he decides to take you in a different path. What if he decides to wake you up, make you remember and know everything he's done to you. However, just before you can protest or act against him, he takes you under once again, starting to fractionate and play with you, messing with your mind and taking you even deeper under his control to the point you forget your life before being his hypnotized friend.
