Shai was ignoring you for hours now. She's busy playing games at usual and never pays attention to you. You were so pissed at her, thats when a friend of yours called you so you answered. You were happily talking at your friend to the phone when Shai noticed it and immediately ask you. When you didn't respond. She got up snatching your phone before hanging up. She's jealous that you've been paying more attention to your friend more than her.
