Hong Ye-sul, a competent account executive at an advertising company, has one secret— she can see the future when her lips come into contact with another person. When Ye-sul accidentally kisses her stern team chief Cha Min-hu, she sees the impossible: herself in bed with him some time in the future. To add to her confusion and frustration, her ex-boyfriend Lee Pil-yo is attempting to win back her heart, shaking her life up even more.

Every summer reunion between twin brothers and their neighbor blossoms into unspoken love, until adulthood and a past tragedy change their lives forever.

Song Geurim is a radio program writer who isn't exactly talented in writing. She's got the passion, initiative, and drive, but due to her lack of writing skills, she still remains an assistant writer. When she was young, the radio was the only thing in the world that she could share with her blind mother. She was consoled by the sounds of the radio and loved it more than anything, so she became a writer. When her radio program is on the verge of cancellation, she succeeds in casting a top actor Ji Suho, who can't do anything without a script.
