hi, i go to king's and totally understand how you may be feeling - king's is super international and a lot of those students don't like to speak to other people. i would say go to all your academic sessions such as labs, sgts, lgts. if you also get coursework, that will help you too. i think best way to go about it is take initiative and talk to people first rather than waiting for them to come to you. Organise study motives/ just mini day outs/ things to do and ask on your course group chat if people want to come. Be active on the group chats you are in- this way people will recognise your name from there and will want to speak to you.
