Zhaohua and Nianxia are sisters.
Although they look exactly the same and speak in the same voice, they each have their own flaws.
One drank and instantly turned into an invincible demonic kisser. The other faltered when the other person was too enthusiastic, and finally blushed and knocked the other person to the ground with judo.
Because of this, they had disputes with different people, and eventually fell in love.
Falling in love is so simple!
