The Original Work Got Ruined After I Quit Being the Sub Male

After regaining memories of his past life, he found himself reincarnated as the childhood friend of the omega female lead Riette from a novel. What's worse, he's a beta sub male lead who, in the not-so-distant future, will clash with another childhood friend and alpha male lead, Cedric, ultimately meeting an unfortunate end.

Edgar decides to step out of this love triangle and support the two's love in order to change the predetermined ending, but—

"Who decided you could just forget? You can't make something that already happened into something that never was."

Somehow, Riette ends up falling for another man, and after going through a rut together, Cedric begins actively approaching Edgar.

"We can't go back to being just 'friends' anymore."

"......"

"I can't do it. I... I can't do that."

Edgar is just confused by this entire situation...
