The Protagonist Can't Be the Villain!

Other protagonists start by losing their memories or having their families destroyed. They search for their origins or the truth, gradually discovering how special they are. But you, from the start, proclaim, "I am a god!" Unfortunately, no one believes you. They'd rather believe you're sick, and your only believer is just trying to appease you so you'll quiet down. Other protagonists are righteous and kind. They either inspire the onlookers with passionate speeches, or move them with small acts of kindness, making people willingly submit to them. But you start trouble one day and pick fights the next. You tirelessly work night and day to wreak havoc. Unfortunately, you've run into a bunch of fools. Not only do they refuse to let you have your way, they're determined to reform you. Other protagonists gradually understand that they alone must shoulder the responsibility and willingly take on the burden of all the people under heaven. But ever since you were born, you've been taught that as a god, you must always be prepared to sacrifice yourself for everyone under heaven. So whenever you hear someone say such a thing, you bristle like a hedgehog, convinced that anyone who says it is either stupid or malicious. So, are you really the protagonist? Even though you're so confident you seem full of yourself, sometimes you still doubt it. Whenever that happens, your senior brother, who also serves as your cook, punching bag, accomplice, medic, confidant, and only believer, firmly tells you, "Yes!" "You're the protagonist." / Theme: I decide my own fate
