Liu Bei (high IQ, vigilant girl) - Zhuge Liang (very possessive of the lord, hypocritical, a fox in the city)
Sun Quan (strong social skills, his mission is to unify the world) - Zhou Yu (no bottom line tolerant of the lord, gentle appearance)
Cao Cao (silent, unwilling to admit defeat, tough guy) - Guo Jia (sick, extremely ambitious, red pupils)
ps: Because I am more cute and filial, the main CP is Cao Guo.
