Even though I had already guessed that Zac would be with Carmen on our wedding night, my heart still ached when my suspicion was confirmed. My throat tightened, making it impossible to speak. I hung up the phone and stared blankly at the beautifully decorated room.

Zac and I met in college. He got my contact information at the campus festival through his roommate and clumsily pursued me for four years. Later, I got lucky and became a singer with millions of fans, while he earned a guaranteed spot at a prestigious research institute with top marks.

Then came Carmen, a lively girl who joined the research institute.

Zac, who had always been steady and reliable, suddenly became obsessed with extreme sports and risky activities like wilderness trekking. I worried constantly about him getting into an accident, especially after a caving expedition where they encountered a mysterious miasma in an uncharted area.
