oh damn it is but that's disappointing thank you anyway!
i mean the story isn't finished yet, we never know
oh my bad, apparently the korean novel where the manhwa is based from is finished already, but idk if they "fall in love" with him
lol its ok ill still read it haha
ok so I havent read this comic so im not 100% sure about the plot but from what ive seen i think its about a guy who gets reincarnated into a novel as some side character or something and tries to get the original ML and FL together but instead they both fall in love with and fight over him
