Don't bully my sister. Tell me.

People have done too many wrong things in their lives! Just like a brand, it hurts to mention it! But people should be fearless when they are alive! Face all the difficulties in the future! But now that everything has happened, we can't change the past! What you can do is to do well what will happen! I suggest you pretend this never happened! Be nice to her afterwards! Make up for her! When she no longer cares about the past, then your mood will be higher! Since you have these considerations, I believe you will be the best sisters in the future.
