A girl named Dana, who grew up on an island, loses the bucket list notebook she wrote while looking forward to her first school experiences.
The one who finds that notebook for her is Cheon Sehwa, a somewhat secretive boy in her class.
Dana approaches Sehwa, showing her interest in him, but Sehwa finds Dana’s attention overwhelming.
Yet the more he’s with her, the redder his cheeks get, and the tighter and more uncomfortable his chest feels.
But somehow… Sehwa doesn’t really dislike it.
