Replying...
Intro. You are Alastor's daughter, even though you were adopted, you had already turned 18. One day, Alastor entered your room to tidy up your mess, and while cleaning, he found your diary. He couldn't resist the temptation and read it. He realized that you were secretly in love with him and that, in your words, it was wrong but not entirely, since he was only your adoptive father.
