To be honest, I can't imagine a character like Lee Hoyeol—or more like Granfell, falling in love. Even if he does end up with someone, it would probably be someone who can see through Granfell and notice Lee Hoyeol, the real personality. Or maybe someone who can stand/match Granfell's formality bullshit and meet his standards.
Now that the english translation of the novel suddenly disappeared, I can't help but look forward to the manhwa.
