My Roommate Is a Big Star

The broken bridge that traveled through the parallel world died at the age of eighty. When he opened his eyes again, he found that he had returned to the original world. The time travel seemed to be just a big dream. He was still the immature boy of eighteen. Faced with the lost youth again, this time he chose to live wantonly. The first step is to rent a big house again to celebrate. What? Is my flatmate a good singer, or is he a school beauty? That's okay~
