Albus Dumbledore made his way through the halls of the historic school of Hogwarts. It was 6:58, he had exactly 2 more minutes left before he would have to face her with every intention of apologizing to her. He went over the plan in his head one last time checking to see if he'd got it right.
"She opens the door. I step inside. She closes the door. I commence the apologizing. She hopefully forgives me. We stay friends. Go to breakfast and continue living our lives like it never happened," he murmured to himself while glided through the halls.

After all that's happened in the past 24 hours. Albus was experiencing a nagging feeling in his head like it didn't want him to apologize, but rather preferred to pursue her. Of course, he would not allow it, he would never and should never jeopardize their friendship for anything (again). It was much too precious to him than anything in the world could ever mean to him. Even though he was the greatest wizard of all time he was still such a barmy old codger for not noticing how in love Minerva was with him. He was mad as a hatter for not taking the hints.

She always took care of him and worried about him. Her colleagues would say that she puts his well-being over her own most of the time. This was it, Albus was in front of the carved oak doors leading to Minerva's rooms. There was no turning back. He had to do this.
"If only I could just modify her memory. Then, I wouldn't have to deal with this, but that wouldn't be right and honest," he said exasperated. He knocked and stepped back awaiting for an answer.

Minerva McGonagall opened the door and saw the unmistakable figure of Albus Dumbledore standing there framed by the doorway. The greatest wizard who ever lived, most accomplished in Transfiguration, defeater of the Dark wizard Grindelwald, Chief Warlock of the Wizengamot, Headmaster of Hogwarts, her employer, her best friend, but most important of all: the love of her life.

Ever since she was under his tutelage she had aspired to be the one his majestic eyes would search for. Unbeknownst to her she had already accomplished that during their first class together when she was the only one to transfigure a porcupine into a hairbrush with no difficulty what-so-ever and with time to spare. You could also say she was blind not to notice his gestures and hints of love.

It would have been easier if he just went up to her and kissed after which he would say that he loved her, but…oh wait! He did! It's just that he ran out the door for dear life afterwards that didn't allow her to process or contemplate anything if it was real and what happened. Well, that's life!

She motioned for him to come in like every morning, but this time she wasn't smiling and was rather in deep thought. Albus took immediate notice of this and started to pray to Merlin and to every single god or goddess he could think of, especially to her namesake, for her to forgive him. As soon as she closed the door and turned around to face him they both started instantaneously:
"I—"
"I—"
They both had an image of embarrassment flicker across each of their faces. Albus was first to recover and said,
"After you, my dear."
"Well. I-I-I-… that is to say…uhm…" she stammered. 'I never stammer!' she thought reprimanding to herself.
