I think she looks equally pretty with and without freckles, but I wonder why she didn’t just stop using makeup once she entered the harem so she could get promoted easily, like she mentioned in Ch. 1. 
Also I suppose Maomao’s reasoning for making herself a less appealing target is understandable. However, the reality is a person’s appearance, age and gender don’t necessarily matter when a rapist is mainly looking for an easy victim. A lot of times they just want a power trip more than anything and it makes me so sad. It sucks that Maomao has to stay so wary from such a young age.
