「Will you keep co-sleeping with me from now on...?」

「...Are you a bitch?」

「Did you think I was a bitch!?」

High school student Nagi Shinonome, who had become unable to feel romantic affection for others, was dozing off on the train.

When he awoke, he found himself unexpectedly sleeping with his head resting against Mashiro Tsurugihana, the most beautiful girl in school.

Tsurugihana, who is known as the 'Doll Princess' at school for her doll-like beauty and lack of expression, makes a surprisingly unexpected proposal to Shinonome.

「Will you keep co-sleeping with me from now on...?」

Since both of them had been troubled by insomnia, Shinonome accepts the proposal.

「You're my body pillow.」

「You're treating me like a body pillow!?」

...or hugging her from behind,

「What's with that leg?」

「I just kind of want to entwine my legs with yours, Shinonome-kun.」

...or having their legs intertwined,

「Do you really feel at ease with me...?」

「I feel so at ease when I'm with Shinonome-kun...」

...or gently asking quiet questions...

Only in front of Shinonome does Tsurugihana wear a sunflower-like smile.

The two, who had no interaction in the classroom, have different reasons for their sleeplessness and different circumstances. Though they seem incompatible, the two are perfectly matched, and through co-sleeping, they tease and comfort each other, eventually falling in love—This love story, renowned for its charmingly captivating banter, begins here.
