How do you fall in love with your rival?

COMPLETED! Nicholai is stubborn, prideful, and absolutely not in love with his husband-no matter what his racing heart says. Their marriage was just for convenience, a mere contract, and he refuses to be another lovestruck fool. But his professor-turned-husband, Alexander, is patient, persistent, and dangerously charming. Too bad his husband is making it really, really hard for him to resist. He swears he doesn't love him. But if that's true... why does it feel like he's already losing? A slow-burn, tension-filled BL romance between a stubborn student and the professor who knows exactly how to make him melt.

To him who shines the most, I offer my heart.
