Draco and Hermione had been dating secretly for an entire year when Draco made it public. Hermione was at a party Ron was throwing for Harry and Ginny's engagement when it happened.
A few hours earlier
"Draco, I'm leaving." Hermione said walking to the door. Draco quickly caught her at the door and gave her a quick kiss on the lips. "Bye, babe. Have fun." He said opening the door for her, but not before getting a good look at her. She was wearing a knee length emerald dress with a low neckline, a pair of black pumps, and her hair was pulled into a messy ponytail. After she was gone he ran to check and make sure the ring was there. After a year of secretly dating he was going to show the public by proposing to her. Okay it was there. It was a 24 karat diamond set in a gold band. He slipped it into the pocket of his black dress pants he was going to wear so he would have it when he left.
At the party
Hermione was having fun. The only down side was that a drunken Ron kept flirting with her. He just didn't understand; even though she kept pushing him away. It was especially bad because his girlfriend, Lavender Brown, kept glaring daggers at her. "Hey Mione. How are you cutie?" Ron asked. "Ron, stay away from me. Why don't you go see what your girlfriend wants." She said. She had been dealing with this for hours. She wished that the party was over, so she could go back to Draco. Little did she know he would arrive very soon. The party got quiet suddenly. Hermione turned around to see crowd part for Draco. He walked right up to Hermione and traced her cheek with his finger. She smiled a small smile. "What are you doing here, Malfoy?" Ron asked stepping in front of Hermione. "I came to ask your friend here something." Draco said slyly pushing Ron aside. "And what, exactly, do you want to ask her?" He asked. "Why don't I show you." He said. Everyone gasped as he bent to his knee and pulled a black velvet box out of his pocket. He opened it to reveal a beautiful ring. "Hermione Jean Granger, will you marry me?" There was another collective gasp. Ron stepped in front of Hermione again. "Is this a joke, Malfoy?" He asked. This time Hermione pushed Ron out of the way. She stood Draco up and pulled his lips down to hers. When she let him go she whispered, "Yes." "Hermione, are part of this joke?" Ron asked, suddenly sober. "No, Ron, me and Draco have been dating for just over a year." She kissed Draco again, and they walked out holding hands. As she passed she saw Lavender suddenly smile broadly and rush over to comfort a baffled Ron by smothering him with kisses.
