He looked at her hungrily. Her eyes narrowed as she smirked. He raised an eyebrow that he had accidentally turned blue in charms. She giggled at him. She walked across the library to approach him. Narcissa walked on past him and out the door. Boy, she had an attitude for a third year. On her way out she winked at him, smirked, and left. Lucius was confused and ran after her.
"Where are you going?" Rodolphus Lestrange asked him.
"After her," Lucius smiled, pointed and ran out.
She was waiting for him, and he came, as expected. She smiled sweetly and ran off through Peeves' corridor, giggling the whole way. Lucius smiled to himself and ran after her. As he chased her she kept looking back to see if he was still chasing her. She finally reached the spiral staircase and ran up as fast as possible to get to the seventh floor. He was confused why she did not get off at each floor. She was running for 'safety' of the room of requirement. He chased her up the stairs all the way to the seventh floor where he lost her as she rounded the corner. He wandered around the seventh floor until he saw Mrs. Norris, and with that he bolted down the stairs and to the dungeons. He stomped in, angrily, to the common room.
"Where did the Black girl go?" Lucius asked angrily.
Looking up from his book, with no expression, Rabastan Lestrange countered, "Which one?"
"The blonde."
"In the corner with Sheila Goyle," Rabastan said looking back down at his book, pointing.
Lucius raced over there. He cleared his throat to make himself noticed. Narcissa looked up, wide eyed.
"H-hi," she said giving a small smile.
"You lost me earlier. I wanted to give you this," and with that he kissed her. He could feel her smile and blush. She pulled away first. "Are you okay with this, Narcissa?"
"'Course. But I don't want my first real kiss to be in the common room," she said smiling.
He held out his arm, "Shall we then?"
She smiled, "We shall."
