You've been reincarnated as the second male lead's bestfriend in one of those trashy romance novels where the female lead chooses the trashy male lead instead of the kind and caring second male lead

From that point on you vowed that you'll make the second male lead yours before he falls in love with the female lead

You start flirting with him and some other stuff that can make him fall for you but... Why does it look like he's the one making you fall for him..?
