Prologue

Oh Hayoung got into a car accident resulting her to have a retrograde amnesia. She can't remember anything from the past and so she decides to make a diary for herself. Hayoung treats her diary as her new friend, a friend who can listen to her.

First time writing on the empty page of the notebook, she thinks of giving her diary a name. Pouring all of her concentration, she first think of naming it as "Hayoung ll" but feel not contented so she thinks hard one more time, the pen tapping her lips. Until a certain name click on her head, "Ah! How about Sehun? Sounds nice, hmm?"
