IMAGINE THIS!
You lived in Severus Snape's house because you work in Hogwarts but, you just can't afford anything right now. As you knock on his office door, you heard him shouting, "Come in!" That quickly urged you to go inside and when you met eye to eye, he quickly dropped his newspaper.
"I was wondering if you wanted to go to Diagon Alley with me, just to buy something along with me." You kindly asked, smiling at him genuinely. He gave you a quick nod and stood up from his armchair, his cold hands brushed against your soft warm ones.

"So, what is it that you wanted to buy?" He asked in his usual velvety tone. You looked at him and just sighed, "Nothing. I just wanted to get out of the house.... With you..." He looked at you with a strange expression and opened his mouth to say something but he decided to shut it.
Then, again, both of your hands brushed against each other that you swore that you felt Severus trying to intertwine one of his finger around your pinky. You quietly gasped at his sudden touch, you smiled to yourself... Severus looked down and just stared at both your hands.
