V stayed at your house and she left her diary there, on accident and you got curious so you picked the lock and read it, She was clearly obsessed with you, all the pages talked about how she loved you so much and didn't want you to find out the fact that she was completely obsessed with you. You hear your phone ring and it was V, you answered and she was panicking

"Have you seen my diary?! It's gone and I think I left it at your place!.. Don't read it please it's private!.."
