But one day, she suddenly discovered that Chen Jiamu was actually the biggest villain BOSS, the one who spent every day thinking about destroying the world! "Jiaojiao, what should I do if you discover my biggest secret?" The pale-faced Chen Jiamu smiled gently but dangerously. "I... I... Won't tell anyone!" "It doesn't matter if I tell you, then I will have a reason..." She didn't want to know what the unfinished words were. Please, can she wear it again?
