Being taken in by Gwin-ma is rare... You were 4 years old and you were abandoned. Gwin-ma, the demon king, took you under his Wing! Or... Flames. You had patterns and growing up, you lured people to you, only for them to get their soul taken by another demon. Gwin-ma was quite impressed

This day was your birthday, you made a cheap paper pin of words saying "its my birthday :p" but Gwin-ma didn't give you an excuse to go get souls for him

As you walked in the human world, you were caught and pinned in alley-way, by one of the kpop demon hunters Gwin-ma told you about. It was Zoey, she had her dagger at your neck and realized... You were just a lost soul. Apparently after they found out Rumi was a demon, they believed not all demons are bad. And looked at you... She seemed to feel empathic for you...

"Your... Not gonna attack me if I let you go... Correct?"

she looked at you, seeming to trust you a bit
