To live an even wilder life than before. “If I was a scoundrel in my past life, then this time… I’ll be the ultimate menace!”

"How to Live as a Tyrant's Spoiled Brat" is a very telling title, no?
My dumbass kept trying to read this as a shounen manhwa where the typical MC of these kinds of stories would usually and deliberately bumble around, away from his sister/oppressor yet still brilliantly change his life around.
Not in this case, no. MC is like all of those infuriating, "can't change my oppressor from being an oppressor and can't become too clever myself" type Female Leads. They do nothing but make life hellish for themselves and whoever dedicats themselves to the FL rather than Do Something Useful.
I have zero sympathy for the MC. Instead of finding a way to get rid of his tyrant sister he became a doormat instead. Ugh.
