Find a hobby that you enjoy that is remotely social, then perform said hobby and comment on it with other people, after talking with the same person a bit ask their name, try not to jump the gun but after a few times of talking with them casually see if they want to do X hobby together then after doing the hobby together for a bit ask them to do something after the hobby one day like get food

Then once you become friends try and meet their friends then kill the original person and steal all of their friends, you can then repeat this until you have enough friends or someone kills you
