just so it be known, yes there is novels with shallow people, but considering this is a Su Luxia story, the female antagonists are driven to the extreme, and each have a niche idea (crazy romanticist, a witch, and a gold digger)
hope she beats them to death directly or indirectly. author laoshi really does wonders to my blood pressure
*usually shallow characters which have one role to play and don't add anything to the story. sort of like the violent childhood friend is only meant to throwing bad remarks and cry, not bad by itself but throw it in a harem and it becomes conspicuous and chaotic if all character have such eccentric parameters
