Get drunk, and spill the beans. Be an idiot about it, but try to be nice. Be sarcastic, cutesy and try to kill them everytime you see them. Give them a handshake. Smile a lot around them and treat them better than you do everyone else. Smile a lot around them, but try not to make it obvious. 2.
Be straighforward and flirtatious. Insult them over and over, but actually mean well. Demand they be your friend. Tell them that they're almost as awesome as you are. You don't like them, but you'll lie and tell them you do for your own benefits. Unless your master orders you to, you wont tell them. Insult them and fight with them.
