My theory is that :

1. Omega did it for fame and money. Because duh, he's the rare water rank. By mating to one of the top highest rank Alpha, the Omega thought he could climb the ladder to stardom easily.

2. Along the way of acting. He actually really did fall in love with the fire alpha.

3. The fire alpha's doesn't care though if the omega really like him or not. His response was indifferent, because he have a damn big pride up his ass. But slowly, he's also trying to open his heart and starting to love the omega.

4. As a progress of fixing his incompetence on bed, the fire alpha then mark the omega, but he still can't react to the omega's pheromone. He was dejected of the result and never touch the omega since then. Because of that, the Omega had to binge on suppresents

5. Then the Ice alpha senpai came back from the outer universe as a better man, and started to woo back the omega he loves. But the omega dodged the cupid's arrow because his heart only belong to fire alpha now.

6. The omega still treats the ice alpha senpai normally though, out of courtesy and for the sake of the good 'ol friendship days.

7. However, because of their close interaction, then the scandal news of the omega and ice alpha got out.

8. The ice alpha didn't denied the rumor, because that was his goal since the beginning anyway. He's probably aware of the contract between the omega and the fire alpha, and thought that the fire alpha was mistreating the omega. So he wanted to be the knight in the shining armor for the omega.

9. Fire Alpha was just about to fall in love with the omega, but then the news about the scandal got out. It makes him thought that the omega was just only trying to toy with his heart. Fire alpha felt provoked, he become pissed and let his mind took control over his heart.

10. He lashed out on the omega and terminated their contract. Then the omega got hospitalized as the aftermath of suppresents.

11. Ice alpha tried to make omega as his own. But he never succeed as the omega was blinded by love. The omega can't see anything but the fire Alpha.

12. The omega's condition got worse. The ice alpha had no choice, he can't watch his beloved stray away from life. So he finally went to the fire alpha, to clear up the misunderstanding and to beg for his mercy to love the omega properly.

13. The fire alpha found out about the omega's condition and he felt guilty. He then drag his sorry ass and apologize to the omega.

14. Omega forgives the fire alpha. The fire alpha got cured. The cure was actually a sincere feeling of pure love.

15. The omega and fire alpha got married, they fucked each other into oblivion. They then had 3 kids and then they lived happily together. The fire alpha died at the age of 72 because of pancreatitis.


P/s : Chill... I see some people wrote down their own theories. And I was just being inspirational tonight, so I wrote a whole fuckin essay. You don't have to take it seriously.
I'm exited to see what the author really have in their own plot.
