“Black-haired bastard….” Why, why is it that the male lead in a romance fantasy always has black hair? And why, why do I always end up falling for the brown-haired one? The second male lead of "The Alliance Marriage," Vailleon Bairs. He is the childhood friend of the female protagonist, Princess Odette, and the current Prime Minister of the Empire. I, the reader, who always falls for the brown-haired male lead, got caught up in my pine tree preference. How could a scholarly Prime Minister defeat the iron-blooded black-haired Northern Duke?! The reader, who had been wailing every night, suddenly possesses the Third Assistant Minister of the Alliance Marriage, Marien Didi. Yes! I’ll make my favorite love come true with my own hands! I’ll make Vailleon the male lead of “The Alliance Marriage!” “Have you thought about dyeing your hair? How about black hair?” “Why do I suddenly have to dye my hair black?” “Because it’s the only way to end your long unrequited love.” If the problem is hair color, then just dye it! If the problem is a lack of strength, then practice! Introducing the ‘Act Like a Northern Guy’ plan. How.Ev.Er. “Not looking back and leaving, speaking coldly while keeping close… What is all of this?” “This is the way to win over Her Highness the Fourth Princess.” “Do you really think she’ll like this kind of behavior?” “I’m sure of it.” “This seems way too violent…” Despite his doubts, Vailleon follows Didi's plan. However, Odette remains unshaken, leaving Vailleon to smile bitterly when the Northern Duke shows up. On the outside, Marien Didi looks like a fluffy cotton candy rabbit, but on the inside, she’s a beast, embodying the original fan-girl pushing her ship forward. Will she be successful?
