This is literally the Kim family complete with V, Haneul, Iseul and Rika.

Rika is definitely the mother, hating her husband for no reason

V is the father, probably talking about how he wanted Jumin's ass since day one

Haneul is the son, stabbing a kid and abusing his brother under the table

And finally Iseul is the daughter, trying to lighten up the mood even if his family went to shit before the apocalypse

This is the Kim family. I swear to God.
