Jack's Sister ( Markiplier X Reader ) - Natatalieee

Overprotected.

Unwanted.

Left alone.

But then cared for?

Jack left her when she was 12; he was 19, before his youtube channel started kicking off. He has always hated saying he has a sister out loud, so he just calls you a friend. When he comes to visit, he also says someone else is visiting...

Who could it be?
