There is a reason why Rahma always wear non-revealing clothes, simple as it, despite having a cute baby face, she hates her body, as she is dangerously thin. As a skeleton, not to mention, her skin has many problems, her elbows are too dark, her arms surrounded by faded cuts, having a blistering skin, her back is covered from it, the reaosn for it is Her Celiac Allergy (it isn't proven until now, but the symptoms are there)
