Dongwoo and Sunggyu are one of those couples you always knew would get married. And, true to everyone's expectations, they did. How could they not? Opposites attract, and the moment Sunggyu- who at the time was about to inherit his father's company and assume position of CEO- laid his eyes on Dongwoo- who at the time was answering phones part time at said company and taught dance full time, up 'till the present-, everyone knew they were probably destined to be. But what's that saying

"So, do you guys visit Sungyeol's parents as much as you visit us?" Of course, that should be a question Myungsoo can answer confidently, with a resound 'yes'. Except he can't because he has never visited Sungyeol's childhood house and he doesn't know why. Sungyeol has always been a little secretive about his childhood. But one day, Myungsoo sees an old photo of Sungyeol. 

So you accidentally took the wrong bag and inside you find...  Sungyeol accidentally took another person's bag after a little mishap at the airport and now he wonders who carries a book about ducks while travelling.

Woohyun is about to go crazy if he sees Hoya and Dongwoo argue one more time. Their fights never get too heated and they never get physical but they leave the air freezing and the tension thick. It's too much.

Hoya is a typical run- of- the- mill university student, surviving on breakfast foods for every meal and barely staying awake during his Film History class. And we don't really know what Woohyun is, but Hoya doesn't want to know. 

Dongwoo's been talking to his penpal, Sungyeol, for so long he can't remember what it was like not to read and write to him every other day. 

Sungyeol finds a book in the library with smudges down the side and he's tempted to call for god knows what reason.    

Dongwoo and Sungyeol are on a long bus ride together ^^
