Hi! Curious as to know what font is used for the the letters 'I AM.' Thanks so much!

I feel like this is someone's handwriting but - there are a few fonts in here and if anyone could identify at least one I'd be more than grateful! Thank you

Hi there! This new single from ARTTM came out, and I've been dying to find this font but I'm not sure what they used. Any help is greatly appreciated, thanks in advance
