Who can define popularity, 1

At first glance, Siwon seems like one of those people blessed by the gods: he's stylish, handsome, popular, and everyone admires him. But at university, he meets the charming Daun, someone who could steal his title as the most popular student... and what he can't stand is that Daun gets everyone's attention! To make matters worse, Daun gets it into his head that Siwon is in love with him. What a load of nonsense! Right?
