My Butler is a Billionaire

Kaito spends his days juggling three dead-end jobs to support his little sister, Nami, dreaming of a life where instant noodles aren't a food group. On his 21st birthday, he wakes up not in his cramped apartment, but in a ridiculously lavish mansion, wearing a butler's uniform. His new boss is Kenjiro Zenyth, the legendary - and legendarily sheltered - heir to the nation's wealthiest conglomerate. The problem? Kenjiro looks exactly like him. Kaito soon discovers the unbelievable truth: they're identical twins, swapped at birth to protect him from a prophecy that foretold ruin for the Zenyth family's 'firstborn'. Now that the prophecy has expired, his inheritance has activated, granting him 'The Sovereign's Eye' - the ability to see the monetary value and potential profit of everything and everyone. Trapped in the role of a servant, Kaito must shamelessly use his new power to guide his naive twin through a high-society battlefield of venomous relatives, all while secretly plotting how to claim his rightful name, fortune, and future. Can he pull off the ultimate switcheroo before their enemies - and his own brother - discover who he really is?
