That's not you

The beginning

The girls, like any other day, were getting ready for bed, but one of them felt something.

-Lisa: Girls, did you feel that sensation? It was kind of weird.

-Jisoo: maybe it's youimagination
Lisa thought Jisoo was right and continued doing what she was doing.
Minutes later, they heard someone scratching at the door and Rose turned around

Rose: What was that?!
Jisoo: -scared- Maybe it was the wind
Jennie: I don't think so, it's best not to dwell on it.

Lisa knew something strange was going on, so she investigated while the others slept.
He investigated the door but found not a single clue, so he gave up.

Every day they all slept together in the same room, that happened until one day...

Lisa: Hi Jisoo!! How are you? Shall we have another sleepover?
Jisoo: I'm sorry, but I haven't been feeling well lately, so I won't be able to.
Lisa: -sadly- Oh okay, I understand. I hope you recover soon!

Jennie and Rose went to Lisa's sleepover and had a good time, but it happened again, only worse than usual.
