Bro you're silly stubborn or should I say you're perseverant?
Joker once said "When you're good at something, never do it for free". If I were to interpret, I think it may be not so bad in terms of you getting to do the thing you love. However, don't sell yourself short :)
The one thing I could think of why they rejected you is the way you talk/present may be too serious to children? Don't punch me bro.
I believe the second interview they've seen your sincerity though! Keep fighting and stay hungry bruh
