The Male Lead of the Tragic Novel Thinks He’s My Boyfriend

I was inside the world of an R19 tragic web novel, “The Flower of Despair,” and I was Saydin Herace, a minor villainous princess of the Kingdom of Herace.
Luan, the male lead, was fated to die due to an outburst of divine power, and his death would bring about the end of the world.
‘I can’t let that happen!’
The only one who could help him was the heroine. So, there was only one solution: to help the male and female leads unite in both body and soul!
Determined to prevent the catastrophic ending, I decided to help young Luan, a war prisoner then.
I desperately tried to avoid the world’s doom, but something went wrong.
Luan looked at me with strange eyes when we reunited years later.

I found myself in the emperor’s chamber when I woke up.
“Wh-why are you taking your clothes off? And why is your body so good-looking?!”
“That’s a relief. You liked my face as a child and still do now. Ah—and you like my body, too, don’t you?”
All I wanted was to be his supporter, the one who cared for him—I never meant to become his first love!
“Your Majesty. While I appreciate you remembering the friend who stood by your side during your hardships in childhood—”
“Does that mean you want me to be your—friend?”
Of course! It would be better for me to stay as a friend and prevent the end of the world!
“That’s a cute way of saying ‘boyfriend.’”
But what do I do? The male lead has completely lost it—because of me.
