Falling in love with my brother's best friend

William Jakrapatr and Est Supha are rivals at school. They seem to hate each other's guts. Especially William. William hates Est the most, he thinks he's too...perfect. However, that is far from the truth.

An enemies-to-lovers story that follows William and Est-two boys bound by childhood rivalry, stubborn pride, and an unspoken connection that never quite went away. When Est moved into William's quiet Chiang Mai neighborhood, he didn't just bring noise and confidence-he brought change. To William, Est was loud, flashy, and infuriatingly good at everything. To Est, William was cold, smug, and impossible to impress. Over the years, they clashed like fire and ice, turning every shared moment into a silent war of words, glares, and video game showdowns. But everything changes when William finally follows his older brother to university-only to find himself roommates with the one person he swore he'd never tolerate again. Older now. Sharper. Still rivals... but something feels different. Because sometimes, hate lingers too long.
And sometimes, it starts to feel a little too much like something else.

William has always been Est's childhood friend-the wide-eyed boy who used to trail after him, eight years younger and endlessly curious. Est grew up babying him, being overly protective, watching him like a little brother who somehow felt like part of his own heart. William was everyone's baby-not just his family's, but Est's too. They grew up together, their families bound by friendship for two generations. But time changes people, and suddenly, William isn't a baby anymore. He's grown-taller, sharper, quieter-and Est doesn't quite know what to do with the strange shift in his own feelings. Let's see how the two of them navigate growing up, growing closer, and maybe, growing into something more.

William and Est are born with matching soulmarks - a rare phenomenon that supposedly binds two destinies. But the twist? They hate each other. Worse - their bond gives them shared abilities they don't understand, and if they stay apart too long, both suffer consequences. They must work together to uncover why their fates are tied... while fighting the growing, undeniable, heated pull between them.
