The water stopped running, and I could hear Alex's footsteps as he got out of the shower. He opened the door, a towel wrapped around his waist, and looked at me with a mixture of surprise and guilt.
I knocked on the shower door, my heart pounding in my chest. "Alex, we need to talk," I said, trying to keep my voice steady.
But I wasn't buying it. I had seen the text messages on his phone, the secretive conversations, the late-night disappearances. I had seen the way he looked at this other person, with a spark in his eye that I had never seen before.
Alex's eyes snapped back to mine, a look of panic in them. "You can't do that," he said, his voice urgent. "You have to promise me you won't say anything."
