Shixun stopped in his tracks to frown at some stranger who was beaming at him, and if he wasn't in a bad mood, he might have actually focused on how cute that person was. But right now, there was nothing but frustration that he felt knowing that this person in front of him, too, was mistaking him for someone and would most likely ask him for a favor. Shixun opened his mouth, but before a sound came out, the other was already talking while putting another book on the pile of books he was already carrying around.
"I'm in a hurry now, so can't talk, but here's the book I've borrowed from you, thanks and see you later at lunch?"
And off the boy went before Shixun had time to react, and this wasn't the first time that it happened. Apparently, he had an identical twin running around on campus, someone who was well liked and had a wide circle of friends. That doppelgänger's name was Sehun and that's about all he knew. He could have easily asked around where that Sehun person was, but he figured people would be surprised to see /him/ out of all people asking that - they had the same face after all.
Luckily for him, it only took him half a day to find his doppelgänger. It was lunchbreak and everyone was filing outside of the classrooms towards the cafeteria in the student union building, and Shixun joined them, too. On his way, he spotted a very familiar face, one that he would usually only see in the mirror, sitting outside on a bench, most likely waiting for a friend, so he headed straight over there.
"Sehun!" He called out and dumped the pile of books and papers right next to the startled Korean, an angry expression on his face. "These must be yours, right?"
