Hinata Saeki, 16 years old, a first-year high school student.
A member of the school newspaper club, she’s full of curiosity and spends her days chasing after her classmates’ latest “scoops.”
One day, she discovers a secret about her classmate Rei Kirishima — the boy admired by everyone for his flawless looks and cool demeanor, nicknamed the “Ice Prince.”
Back in middle school, he was actually overweight and mocked by the girls!
When Hinata catches a glimpse of Rei’s clumsy side — like the moment he drops his pen and blurts out, “…Ah!” while blushing — her heart starts to race.
Finding him “so cute!”, Hinata begins writing a secret observation diary about him and soon becomes completely captivated by his gap between cool and adorable.
As the girls around them squeal with excitement and classmate Reina Nishikawa’s jealousy leads to petty harassment, Hinata pushes through it all, gradually growing closer to Rei.
When Rei murmurs with a faint smile, “…Hinata, you’re such a weirdo,” Hinata’s heart won’t stop fluttering!
A youth romance full of humor, secret discoveries, and the sweet spark of first love — capturing the special feeling of knowing someone’s hidden side.
