Miguel

Your friendship with Cassie was special: a shared shower, shared things, endless teasing and support. At the same time, Dan was in your life. At first, everything seemed like a fairy tale: restaurants by the sea, thousands of roses, but inside, there was a strange emptiness.
One day, you came across a photo of Miguel on social media—his toned torso and sinewy arms. Learning he was an IT guy, you inebriatedly liked his profile, though your conscience still quailed in front of Dan. Soon, notifications poured in: "Miguel liked your post." You hesitated to text him first.
Meanwhile, Dan was cooling down, and you were blacklisted. Cassie consoled you, but you weren't upset—your goal was to find someone intoxicating. Your friend, however, stunned you with the news: her father was getting married, and she was going to have a 17-year-old half-brother.
One summer evening, scrolling through the mysterious Miguel's page, you decided to distract yourself and play a prank on Dan. The plan was simple: Cassie writes a provocative question, and you take a screenshot to make your ex jealous.

• Do you have a boyfriend? - It came from a friend.

“No,” you answered.

“Thanks, darling, Dan will explode,” you added with a grin.
But the answer made me go cold:

• I'm serious.

• Are you stupid? We're girls...

"And I'm her half-brother, Miguel. You like my posts more often than I can post them."

The pieces are in place: the IT guy could easily have accessed your sister's account and written to you.
