Kaká’s wife left him because “he was too perfect” and she couldn’t stand it. That’s why many fans comment on his posts to give him advice on how not to be so perfect.
A world champion, Ballon d’Or winner, and remembered for his elegance on the field, Kaká is seen as a very proper figure, always polite, family-oriented, calm, and far from controversy.
Some of the comments are: When she says “I love you”, reply with a “thank you”. Drink juice straight from the bottle. Start hanging out with Neymar. Leave the toilet seat up, etc.
The trend quickly went viral because the real joke is that many fans feel they can’t find any obvious flaws in Kaká, since he really is too perfect.
