breaking bad is about man self-isekaiing

the cancer diagnosis is his truck-kun

he goes from Normal Guy Teacher to Dark Lord of Meth,complete with:

secret special power (chemistry knowledge that's somehow godlike in this world)

New badass name

Increasingly OP abilities that shouldn't work but do

every woman exists just to react to HIM

starts with nothing but rapidly builds an empire

Plot armor thicker than a bowl of oatmeal

everyone becoming NPCs who act stupid so he can win

the wish fulfillment is identical - sad man with boring life suddenly gets to be the specialist boy who wins everything and is feared/respected
