"The one confession you lack to make it a draw... Shall I give it to you?"
Chikage and Haruto have always been competing against each other since elementary school. They have a competition to see who can get the most number of confessions before their high school graduation...?!

... A few years later.
Despite always declaring it "A competition!" every time they meet, they went down their own respective paths with Chikage as a model and Haruto as an actor.
Coincidentally, the first drama recording that Chikage stars in happens to be alongside Haruto...

It's a heart-throbbing love story where the clumsy duo's worlds of love and work collide!
