This is a semi-realistic fanfic with Harry Styles as the male protagonist.
Solemn warning: the heroine Eve Sivan is twelve years older than Harry.
Eve and Harry are two extremes, but they are attracted to each other without knowing it.
PS: The article is written from the perspectives of Harry and Eve, but it is not the first person. Eve's perspective develops from the very beginning, and Harry's perspective looks back from the very end until the two people's timelines intersect.
How can I fall in love with you? 12 Years old is an insurmountable gap.
