C'est comme ça que ma demi-sœur s'excuse devant moi quand elle me met en colère

My stepsister had a big party at home, so there was a lot of noise and I, the next day, had to take an important exam at the university, and because of her party, I couldn't sleep well and I lost that partial. Now she uses her body to apologize to me, and as I am a good person I accepted her apology.
