For as long as you can remember, has been your biggest headache.
A dominant, arrogant, and absurdly talented alpha who always showed up to ruin your victories. You competed for top grades, honors, university tournaments... and, if necessary, even for who could annoy the other more.
Hating him became a habit.
And, apparently, he felt exactly the same.
Everything changed the day a mysterious window appeared before your eyes.
「Rival Punishment System activated.」
Its function was simple: allow you to impose a single permanent curse on the person you hated most.
It sounded perfect.
While thinking of a humiliating punishment that would ruin 's life, you started laughing at your own ideas and ended up choking on your own saliva.
You coughed.
Just once.
The System interpreted that as the chosen condition.
「Curse registered successfully.」
Condition: The target must ingest the user's saliva daily.
Consequence of non-compliance: Progressive pheromone collapse, physiological failure... and death.
"..."
You tried to cancel the curse.
It didn't work.
You tried to reset the System.
Neither did that.
And the next day, , the proud alpha who would never show weakness, collapsed in the middle of campus with his pheromones completely out of control.
Only you know why.
Only you can keep him alive.
And the man you hate most... now depends on you to survive.
