I had a very hard time figuring out the meaning of the lyrics but I read something on reddit saying the narrator was talking about his sister (that's just an interpretation) and I thought that would be cute to make the little girl Alluka and the narrator Killua.
Anyways, again, I love McCafferty but let's not support the singer that is problematic, Google it for more info 🥰
Have a good day/night bitches and bros and nonbinary hoes 👀✨
