How to implement a dynamic list in the database model?

Question

Database design

Good afternoon, I'm new to the backend and therefore, perhaps a stupid question. I want to create a training REST Api service in Django that would simply store information about the user.
The user in JSON can be represented like this:

{
   "citizen_id": 1,
   "town": "Москва",
   "street": "Льва Толстого",
   "building": "16к7стр5",
   "apartment": 7,
   "name": "Иванов Иван Иванович", 
   "birth_date": " 26.12.1986",
    "gender": "male",
   "relatives": [2,4] // id родственников
}

How, in this case, to create a database model in which relatives can be empty, or can have several id? With everything else, more or less figured out.
Thank you.

You need ManyToMany
