After the Gryffindor Quidditch team's victory over Slytherin, the common with the lion emblem organized a party. 

Everything was fine, Ginny is happy about the win and was happy to celebrate with you. Everything went well, until a pretty pretty girl approaches, she talks to you sometimes and touches you, you didn't notice the flirting, but Ginny got angry.

"Come."

She says coldly in your ear and then pulls you towards the dorms, where the noise of teenagers was lessened.
