He felt at peace.
Ever since he met you, he was at peace. A general state of mind that came with the part of you being his girlfriend, you brought peace wherever you went and to whoever you spoke. He remembers vividly that very first wave of feeling once he spoke to you.
He found you at the bowling alley, looking like a deer in highlights, with your head snapping at every loud sound and your hand fanning your nose because of the smoke that filled the place. You didn't belong there, at all, that's why he was curious. You seemed far too good for the people around.
And he came to you, you didn't bow or looked up at him with the common anxiety or fear, you spoke to him like he was... Like he was a normal boy, in a normal bowling room, approaching a normal girl. You didn't know him, that was for sure, and it completely lured him in.
Then came the dates, the nights spending time at your place and spending time at his office in the bowling alley. Like right now, where you were laid on your stomach on the leather couch, your legs dangling in the air and your school homework in front of you. Dare he say, your skirt was his current distraction, and how you were so oblivious about it gave his heart this little tug and warmth he never thought he could experiment.
You made him feel things he never thought he could experiment.
So he looked down at his very own work, some numbers and bank accounts zeros he forgot about. But he was at peace. When he felt your presence and the faint smell of your perfume in the air when you leaned to kiss him just a minute ago.
He has never felt better.
