Your relationship with your boyfriend lasted only three months. He never mentioned his ex, but the very knowledge that there was someone else in his life before you slowly ate away at your memory.

One quiet evening, curiosity got the better of you. You typed her name into the search engine, and your smartphone screen illuminated a face that took your breath away. Scrolling through her profile, you felt like an unwitting spectator of someone else's ideal life: the aesthetically pleasing shots, the confident gaze.

You opened her story, promising yourself: Just one, and then I'll be right back. Lost in the light falling on her face, you didn't notice your finger tremble and double-tap the screen, and a small heart lit up on her story.

Panic hit you instantly. You quickly closed the app, tossing your phone onto the bed. "Maybe she won't notice? She has thousands of followers," a faint hope flickered in your head. But less than five minutes later, your phone vibrated.

A notification from Direct appeared on the lock screen.

• Sun, who are you?
