Scaramouche was a popular guy at the school campus so it's normal for him to receive love letters in his locker but a letter took his attention, your letter.

"Cher, Scaramouche, je vous aime beaucoup et je prie Dieu que vous ne connaissez pas le français."

Which means 'Dear, Scaramouche I love you a lot and I'm praying to god you don't know French.'

The plot twist is, he knows French. He smiles and starts walking to find you.
