*Harry had a crush on her since first year, which is he had dragged out if bed when he saw Peter Pettigrew on the Maraurders Map.

When they saw no Peter and instead saw Snape walking towards them on the map, Harry panicked.

"Play along," he whispered to her before turning off his wand light.

Suddenly, his hands were on her waist as he pushed her against the wall. He kissed her, making the kiss fierce. Snape think they were snogging.
