A father travels across the world to find his child, encountering all kinds of gangsters, scoundrels, liars, and lunatics, and having all sorts of pleasant and unpleasant transactions.
Gangster: In which eye do you think I look like your son? I think you look like my wife
(Not the real father and son, the two people who joined the group to keep warm got lost, the first world had too much emotional lines)
Scoundrel: Aren't you my dad? Come on~ I just don't have a place to live today.
(The emotional line in the second world is stable)
Liar: I am your son and you are my father. I am really your son. Wait for me (Third World Wife Chasing Crematorium)
Madman: I don't want anyone but you.
Intention: The purpose of being together is to double happiness
