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?!?!
