Morning, From an Immature Night

Popular college student, Seung-Jae Lee's got it all, when it comes to wealth, connections, physique, but everytime he spends a night with a girlfriend, he immediately gets dumped. After one of these break ups, Seung-Jae spends the night drinking and on his way home runs into and catches up with Ui-Seong Kim, a friend from high school. Seung-Jae drunk-confesses all of his problems and Ui-Seong convinces him to re-enact everything that he tried with his previous girlfriends, causing the two to end up having sex. The next day, Seung-Jae realizes he did something crazy yet asks how last night was. Ui-Seong replies, “I don't know, maybe I'll know if you show me one more time,” tempting Seung-Jae again.

Can Seung-Jae stay friends like old times while still having sex with Ui-Seong? But unexpectedly, Ui-Seong has a secret to reveal, but it's become a shade...?
