As Promised, Where Is Little Transparent?

Before my rebirth, I was the taciturn Lu Yanyue in my class. After failing the college entrance examination, I was mediocre for most of my life. On the first day of my senior year in high school, I tore off my gray disguise, raised my hand to run for class president, joined the debate club, and blocked the top students in my grade after school to ask questions. Everyone is surprised by my changes, but I only know that in this life, I want to live a vigorous life. Until the school boss who was the second in grade in my grade stopped me in the corridor: "Lu Yanyue, who are you?" I smiled and said nothing, but he whispered: "Because I am back too... This time, I want to win with you."
