Every relationship had its secrets, Michael knew that. He just hadn't known what was yours.
His mind kept on running in circles trying to decipher what kind of things you kept under wraps. Maybe it was a dark past, maybe you were cheating, maybe it was something so twisted he probably shouldn't even be speculating about it. His stomach twisted into painful knots just thinking about it.
It wasn't that he wanted to think ill of you, he didn't, he loved you so much it hurt and yet the feeling persisted; but he knew that nobody was perfect. And he wanted to know.
He didn't knew how he should be feeling now that he found out that your secret was actually harmless. You wrote fanfics. It was such a silly thing, and he could live with that. God, he really could. Either way, and regardless of it, he still felt for you.
He didn't minded it, even if he was taken aback by it at first because not only he wasn't expecting it but he was expecting something much worse.
Thankfully, it was just you being you. The same you he loved.
