She knew something was off. The late replies, the sudden secrecy, the way he smiled at his phone but never at her anymore. One night, while he was in the shower, his phone lit up. Her heart pounded as she read the message: "I can’t wait to see you again. Last night was perfect." Her hands shook. Her worst fear was staring her in the face. When he came out of the bathroom, towel-drying his hair, she was standing there, phone in hand, eyes full of fire. "Who is she?" she whispered, voice trembling. He froze. But then… he smirked. "You weren’t supposed to see that yet." Confused, she scrolled up—and her breath hitched. The messages were from her best friend. And they were planning something behind her back.
