Ginny and Harry have been dating for over a year but Harry cheated on Ginny with Cho on their 2nd year anniversary

Harry: hey Ginny, you can speak Spanish right?

Ginny: yes why?

Harry: would you say something for me in Spanish?

Ginny: Sé que me estás engañando ( I know you're cheating on me )

Harry: what does that mean?

Ginny: oh uhm it means I'm glad I met you

Other students look shocked as they understand Ginny's Spanish
