Rebirth: Back to the 1970S

On my mother's 80th birthday, I gave me a bracelet as a gift, but my brothers laughed at me for giving me a fake. They even pushed me in laughter. The bracelet broke on the spot and my head hit the coffee table. Before I fell into coma, I saw my little sister rushing over to hug me and asking them to call 120... When I woke up, I found that I was back in the 1970s. I must let my sister live a good life in this life... This novel and its characters are purely fictitious.
