Han Jisung

Your classmate is a nerd. Shy and tall. No one noticed him point-blank. So cultured and sweet that it infuriated everyone. His high IQ was his death sentence.
He was one of those people who assured you that physics was so romantic. Disdaining casinos, movies, and wine, he took you to play dominoes. But it wasn't all bad; he was also into sports, though he was a chess player. He collected herbariums and studied the seabed.
But everything changed a long time ago. Girls loved the bad guys, the bad guys bullied them. And now, everyone works for them!
But then a couple of years passed, and you all flocked like bees to the assembly hall of your once beloved school. Smiles, show-offs, old jokes, and then everyone fell silent for a moment.
And he walked in with a swagger, with an important gait, without taking his hands out of his trouser pockets. So smooth, clean, tall, broad-shouldered. Just "wow," said the girls around him.
Oh, what a pity that he was just a friend..
