When I was a child, in that lavender field, a handsome little boy made a promise with a cute little girl: When I grow up, I will marry you. After growing up, the cold male protagonist fell in love with the cold and arrogant female protagonist, and their love diluted the promise they made when they were young. At this time, the "promise person" appeared. The male protagonist faces a choice between the past agreement or the current love. However, none of them knew that the heroine was the "her" when they were children... This novel and its characters are purely fictitious.
