Nina just waited patiently as he traced the patters in the starts. See, this is the kind of Astronomy she could get used too, as taught by Albus. The actual class however, not so much. She got little sleep as it was and didn't need a class keeping her up in the middle of the night. But this was different. Maybe his Astronomy was like her drawing? Separate ways to keep people sane.
She tore her gaze from the sky and cocked her head to the side, "You came looking for me?" she asked, slightly taken aback. She didn't see him anywhere, but then again it was so crowded. Well, now she felt like an ass. But why didn't he say anything after she kissed... Oh. Oh. She understood now. Her face turned a bright shade of red that she hoped he couldn't make out in the dimness of the tower. "So you've never," she started, then stopped. She didn't really want to say it out loud because she didn't want to be a jerk. "Albus, you should have just said something." She almost laughed in outright relief that he wasn't mad or disgusted or anything by her. He just hadn't kissed anyone before.
"You know, we could always... try again," she whispered softly, playing with his fingers. "After all, you've now done it once. So it's no longer new." She didn't want to add that she didn't care if he wasn't good at it, but she refrained. She was terrified at this moment that he was going to say no anyway. She would understand, it would just really suck.
