Demanding forgiveness and a fresh start is not a good look.
If you are truly sorry for your actions, you actions will improve. You will not do it again. You will try to make it right. You will try to make up for it.
Lashing out in anger that were you caught or that you are being called out on your actions is definitely not a good look either.
Yo will not diminish your actions. You will not make excuses for your actions. You will not find a way to assign fault to the other person.
