how to add a friend and see the list of friends?

I searched for a very long time, but I could not find any options
who knows, can you help?

@KAWAII_WARRIOR, if you want someone to be friends and diplay his/her name in your friend's list, follow them through their profile and all whom you follow will be displayed in the friends list!
