There was a summer training class, and I accidentally filled out the information registration form and didn't want to go. Is it okay if I don't pay and sign up?
Summer training courses are mostly private training institutions. If you fill out the form and don't want to go, then don't go, right? At most, your new information is leaked, and the rest doesn't matter, and you won't replace him. If you don't pay the fee, he will urge you to pay it. If you really don't hand it in, you won't learn at most, will you? There is no bad influence on him.
