another couple of things to note:
First, as far as “the reading” is concerned - it’s not asking you how to phonetically pronounce it (as has been mentioned before). Try to think of it more as “how is it spelled”
Secondly, if you know english, you definitely run into this problem WAY more than in japanese. Take the word knife for example - we all know it’s pronounced NAIF, but speaking in terms of learning the language, you would never ask someone to write it out the way it’s pronounced … rather, you would ask them how it’s spelled so they get used to writing it correctly.
It’s not about phonetics, it’s about using/writing the kanji + particles correctly
