I’ll Protect the 2nd ML’s Love

I passed out after a day filled with misfortune. When I later opened my eyes, I was inside my favorite novel. Unfortunately, I was reincarnated as the villainess who was ruined after wreaking havoc due to her obsession with the male lead... That doesn't matter! I won’t become a villainess, and will instead match my favorite character in this novel, the second male lead, with the heroine! But this is... harder than I imagined?!?! “Are you alright?” The captain of the knights who was supposed to be the heroine's bodyguard ended up as my own. “I got it for free on the way here. Eat it.” The guy who is supposed to help the two end up together keeps going off track by 3000%. “Are you out of your mind? I told you to be careful!” And the male lead who is supposed to hate me is annoyingly hovering around. ”I'll feed you, Lia!” Even the heroine had no interest in anyone, not even the original male lead?! Not only that! -“Thank you. I'll treasure it.” My heart started beating for Ain who suddenly appeared without warning! ...Will Lia be able to save the second male lead's love?
