Exposing My Best Friend’s Secret Wedding To My Fiancée

From the back cover

For years, a quiet couple's account has chronicled small, tender moments: two people bickering over takeout noodles, watching stars from a mountaintop, caring for each other through fevers. The narrator follows it anonymously, moved by a love that looks exactly like the one he imagined for himself.

The night before his wedding, the account posts a final update: ten years of loving each other ends today, and the woman is now someone else's wife. The attached photo shows the narrator and his fiancée, taken at the bridal boutique, with his best friend Ethan smiling beside them. Calls to Chloe and Ethan both go unanswered, and a search of nearby posts leads to a private account whose name suggests the intruder is the one who is not loved.
