Bad chemistry

Lee Minho and Han Jisung have known each other for as long as they can remember. Their families have been close since childhood, which means they've practically grown up together.
Unfortunately for them, growing up together didn't exactly make them best friends.
If anything, it made them each other's biggest rivals.
From childhood arguments and petty competitions to fighting for the top spot at school, Minho and Jisung have spent years trying to outdo one another. Minho thinks Jisung is loud, reckless, and impossible to deal with. Jisung thinks Minho is arrogant, irritating, and far too pleased with himself. They know exactly how to push each other's buttons. They know each other's habits.
They know exactly what to say to start an argument. And after years of rivalry, they've gotten pretty good at convincing everyone-including themselves-that they can't stand each other.
But as they get older, something about their rivalry begins to feel... different. Maybe it's the way their arguments don't end quite the same anymore. Maybe it's the moments neither of them talks about. Or maybe there's been something hiding underneath all those years of competition that neither of them was ever supposed to notice. They've spent their whole lives trying to get under each other's skin. But what happens when they finally start wondering why?
