I gestured with my chin towards a nearby file rack . " Stick it there . " He quickly scribbled his name on a sticky note , slapped it on the cover , and sprinted towards the science building . Unfortunately , Andrea , who was coming downstairs to grab a package , saw the whole thing . She pretended to just be walking by but as she passed my window , hér hand darted in and snatched the notebook . I was organizing some other files and didn't notice at first . When I looked up and saw the notebook was gone , my stomach dropp- ed . A quick check of the security footage confirmed my fears . Just then , Caleb came back . I quickly told him what had happened . At that exact moment , a video call from Andrea came through on his phone . He answered , and her voice , artificially sweet , poured out of the speaker . " Caleb , I got what you wrote for me this time . I'm so touched ! I can't believe you put in so much effort to write me a love letter using math formulas . " Andrea prattled on , but I could see Caleb's face twisting in disbelief . " I took a picture of the formulas and posted it on my story , haha ! None of my friends can figure it out . " Caleb's face went bone - white . " Andrea , what the hell are you doing ? " he hissed . Andrea's happy tone faltered . " W - what's wrong , Caleb ? Why are you being so mean ? " He took a deep breath , steadying himself on my office window frame . " Delete that post . Right now . And bring that notebook back to me . " Confused , Andrea's eyes flickered and saw me in the background . She exploded . " It's you again ! What did you say to him this time ? " Seeing her get jealous at a time like this , Caleb lost it . " ARE YOU INSANE ? " he roared . " THOSE AREN'T MATH FORMULAS ! THAT'S MY UNPUBLISHED CORE EXPERIMENTAL DATA ! " " That's not a love letter ! If that data leaks , the entire project is ruined ! We're talking millions of dollars in damages ! " The words hit Andrea like a physical blow , Realizing the catastrophic scale of her mistake , she hung up and frantically deleted the post . A moment later , she came running downstairs and shoved the notebook into Caleb's hands . Caleb didn't even spare her a glance . His entire focus was on the notebook , flipping through the pages . He let out a long sigh of relief when he confirmed it was undamaged . " It's all my fault , I shouldn't have left it out , " I said , shooting a pointed look at Andrea . " Don't blame yourself , " Caleb said , his voice tight . " This notebook would be useless to a normal person . I just ... I never imagined someone would mistake it for a love letter . " His gaze towards Andrea was now completely devoid of its former warmth Andrea , mortified and furious , rounded on me again . " She must have put it there on purpose for me to find ! Caleb , listen to me , she Chapter 2 s just trying to drive us apart ! "
