Professional baseball player Dong Chi-Sung (Jung Jae-Young) experiences yet another unpleasant ending to a romantic relationship.

He goes to the hospital on the same day and learns from his doctor that he has a tumor and only has three months left to live. Dong Chi-Sung goes to a bar to drink his problems away.
The next morning, Dong Chi-Sung wakes up to find himself in a motel room with the bartender Han Yi-Yeon (Lee Na-Young) from last night. Chi-Sung asks Yi-Yeon how he got to the motel and Yi-Yeon explains carrying him in a box to the motel after he passed out. Their awkward relationship begins.
