After the Exchange of Mortal Enemies, We Teamed up to Beat the Scumbag

When I woke up, I became the person I hated the most - Mu Zazao. The cold and proud face in the mirror made me want to smash the mirror. She was my number one love rival in high school, fighting for my school pride, fighting for my first place, and always opposing me. But now, I'm standing in her room wearing her pajamas. The phone rang, and the note was "Baby Xuan", the school sweetheart Chu Zixuan who I couldn't catch in my previous life. He sent a voice message: "Zhao Zao, please help me do my math homework today. I love you." I sneered and replied: "I love your mother, write it yourself." Wait, I became Mu Zaozao, what about the original Mu Zazao? Could it be... That it's penetrated my body? !
