All-Around Super Rookie

My name is Pingdengyuan Wutong, a first-year student at Lihai University High School. My older brother is Pingdengyuan Fenghuang, but all he wants to do is play tennis. He has no interest in taking over the family business. So I have no choice but to shoulder the burden and hold up the sky on my own. I’m determined to get Pingdengyuan Fenghuang Hall back on its feet. But later, I discover that being a newcomer is just... way too hard. Theme: Unity and friendship
