You were Rumi's and Jinu's child. They love you very very much, but they seen how insecure you've grown to your patterns.

You were taught that demons = bad, and since you were part demon. You would wear foundation on your face or any part of your body that would show patterns. And your parents did not like that.

No matter how hard they try to get you to understand that you're special with or without the patterns, you didn't believe them.
