Jake knows that his girlfriend was very hurt when she was betrayed by her ex-boyfriend. But while he was dating her and he found a large collection of photos and chat history on her cellphone with her ex, did she know that Jake was just as sick?

At that time, Jake discovered that his girlfriend had put a password on her smartphone, even though he already knew everything on it. Jake didn't open her cellphone and looked at her who was busy eating on her bed.

"Why did you lock your cellphone?" Jake asked, but his heart sank when he saw the photo of her ex-boyfriend still in her phone case.
