At Exo's dorm,   "Sehun ah, how come you're later than us?" Luhan asked, dragging the luggages upstairs.   "Oh, I had extra class and..." he trailed off.   "And?" he urged him to continue.   "I... I sent Krystal home before I came here" he answered shyly, rubbing his suddenly itchy nape.   "WHAT?!" Kai shouted, out of nowhere.   "You sent Krystal home?!"    "Neh" Sehun nodded, wondering why he's so surprised.   "How about her Ilhoon oppa? Didn't he come to fetch her?" he asked in surprise.   "No, I guess he had some problems" he explained,  "I saw Krystal standing at the gate when I came out. It's already late so I offered to take her home. And she accepted my offer"   "She accepted?" Kai asked questioningly.   "Who accepted?" a girl wearing a pink minidress wondered, "Oh my! Have you already proposed, Sehunnie?"   "No!" Kai and Sehun said in unison.   "If it's not, then..." she shrugged it off with a sigh.   "Welcome to Seoul, Tiffany noona!"

That's weird!" he rolled his eyes.    Eyeing the two. Jonghun eating chocolates that Tiffany bought and Tiffany talking to Baekhyun beside him.   He got the shock of his life when a terrifying thought entered his head.    "OH MY!" he gasped loudly, gaining attention from everyone, "HYUNG, NOONA, ARE YOU TWO DATING?!!!"   Jonghun choked on the chocolate he's eating and Tiffany knocked on Sehun's head to make him regain his senses.   "Yah! Have you gone crazy? Why'd I date a playboy like him?"    "Ani..." he voiced out, "Since Jonghun Hyung's coming here unusually and he told me that he's here to welcome noona, so I've nothing but the thought that you two were dating. Mianhe"    Sehun lowered his head apologetically.   "Yah! Coming here isn't unusual thing. I often come here once a week or may
