Phantom of the Opera

Lee Felix had always known about the no-dating policy in the K-pop industry, and it never really bothered him. Since the moment he packed his bags for his flight to South Korea, he had promised himself that he wouldn't let anything distract him from achieving his dream-definitely not emotions or any romantic interests.
But what if that romantic interest wasn't really someone Felix could have a future with? Or any kind of real relationship with, for that matter?
What if Felix never really had a chance, and he had fallen from the very first day?
What if the future awaiting Felix in South Korea turned out to be completely different from what he had expected for himself?

What if the most famous and popular idol, Lee Felix of Stray Kids, was never interested in anyone because he already has a secret lover since he was young?

Or-
Felix was excited yet terrified to move to South Korea on his own. He never expected to meet a friend only he could see. Never thought they would become inseparable. Never thought he would fall head over heels for that friend.
And he definitely never imagined that this very same friend would make him throw all idol rules to hell and become his future husband.
