Kang Soo Mi is an intern in the Medical program at Seoul University. The cons of persuing such an assiduous career is not being able to maintain a good relationship with her impatient boyfriend, Do Kyungsoo, who is a major in Interior Designing. For two straight Christmases, Kyungsoo had to spend it alone because of Soo Mi's schedule. How will this year's Christmas be any different?

"Tomorrow? Err.." she hesitated. Kyungsoo's hope went from 100 to zero. Another date rejected, he thought. He clenched his teeth in frustration trying to keep his anger level down.

He let out a long sigh, "It's fine.. I'll just go to the movies with Chanyeol.." he gave her a short kiss before he departured. 

"I dont want to spend this Christmas without you again..." he sighed.
