Changmin has to choose between his girlfriend Seohyun, a lighthearted and sweet girl, and Yuri, a mysterious girl who he seems to have fallen for but doesnt love him back. ForewordI kept thinking of her smile, that rivaled the beauty of the moon. Most people wouldve compared it to the sun, but she was different, because everything that I associated her with had to do with the night.Yuri, was her name. And I was completely, head-over-heels in love with her. There was a problem with that though, and it was my girlfriend Seohyun.I loved her too. Her and Yuri were equally beautiful, but they were complete opposites; where Yuri was night, Seohyun was day. To sum up my dilemma in a single metaphor, I had become a night owl, but I was dating the sun.I would give Seohyun up for Yuri in a heartbeat, but Yuri didnt love me back.
