Thank you! I couldn't see it ending perfectly happy. Among other things, Draco did arrange for Keatson to die, and lie about it. That's...not exactly something that Harry can forget, at least at first. He'll need some time to see that Draco's feelings for him are genuine.

Ron saw emotions in Harry's face that he hadn't seen in a long time, and which made him decide that Harry was where he needed to be and Draco was all right for him.
