Reborn in 2012

On December 21, 2012, the end of the world that so many people feared did not come, but it ushered in the end of our protagonist. Unfortunately, he died in a drunken fight, and then he was strangely reborn, returning to the beginning of the university a few months ago. After waking up, he was surprised to find that he actually had a brain that was even more genius than a genius, skills that were unrivaled in the world, and an extremely handsome face. But trouble has come. Do those relatives and friends still recognize me?
