Can you hear me?

-Sehun P.O.V.-
"Hey Seah! Come eat with us!" Kai yelled at her as she walked by in the hallway.
Kai looked confused at her completely ignoring him but I knew why she really did it.
"Did she just ignore me?" He said hurt a little, looking around the circle of guys on the floor.
"Its probably because she's still not use to that name, when she is in America she goes by Marissa. I'll go get her." I said and got up.
I walked down the hall and caught up with my sister and put a hand on her shoulder. She turned around surprized and then smiled. But from behind her I saw a group of girls and I knew exactly who they were.
"The guys wanted you to come eat with us, they are in the practice room you just passed." I told her keeping her focus on me so she wouldn't see the girls.
"But.." She said pointing to the recording room when I started to push her towards the practice room.
I pushed her into the room and felt a tap on my shoulder.
-Kyungsoo P.O.V.-
I was turning down the hallway to the practice room when I saw Sehun pushing Seah into the room. Yes! This is my chance to get my phone back. But a group of girls surrounded Sehun and I stopped walking and stood back behind the corner.
"Is that who I think it is?" One of the girls asked Sehun tapping on his shoulder.
"what are you talking about?" He said nerviously.
"You know what I'm talking about, your little brat sister. She looks very good after what happened to her that night."
"Just stay away from her, she's not here to be a trainee so you don't have to worry." Sehun said getting very serious.
"So you guys are on good terms now?" She asked him.
"*sigh* She has no memory about what happened that night." He said a little softer.
"So you don't want her to see us in case she remembers? Why would I care if she remembers?" She said getting very close to his face.
"You guys also did bad things to her that night, we could have reported you to the police." He said and the girls gave him evil looks and walked away.
What have I just overheard?
