At first, Neville that that Hannah would pull away, smack him, get angry... anything like that, because he was the only one who missed this, missed them, wasn't he? But she didn't do any of those things, she was kissing him back and the familiar bunching of his robes in her small, capable hands was welcoming. So much so that he kissed her again, fervently and ran a hand through her hair and pulling her close at the same time.
Hannah was still kissing back and it was like when they were first married... and it reminded Neville how much he hated to be asked the question 'why is it you two divorced then'... when he didn't really have a valid answer other than 'we're better as friends'. He often wondered what he had done, because in his eyes, Hannah didn't do anything to make them split up, so it must have been him.
He stopped his brain from delving too deep into wonder and only kissed her softly, once more and leaned his forehead against hers and cupped her face in one of his hands. "I... I missed you, us. I'm sorry, I didn't know how to say it or when to say it. Didn't know if you feel the same, but, I miss you." Neville swallowed hard and closed his eyes, still holding onto Hannah in the middle of the living room.
