Terra: Charisma 999, But Something Seems Off

Cao Chao transmigrated to Terra, where everyone had transcended lowly tastes, but got a System that happened to require interaction to grow stronger. Good news: His stats showed 999 Charm! 999 Charm? How could that be?! Wouldn't the super-Terrans crush him to bits? Bad news: Ch'en Hui-chieh, Swire, Lin Yuxia, Greyy, and Texas were still completely uninterested. Good news: Hoshiguma and Nian loved spending time with him, and even Mrs. Wen was very kind to him, treating him like family and planning to set him up with Ch'en Hui-chieh. What the hell! System, you're discriminating based on my name! How can you secretly call me a Cao thief?! Besides, neither Big Sis Hoshiguma nor Big Sis Nian is married. Are you judging by age or something? ...Speaking of which, how old is Kal'tsit?
