Summary
Seiya Kou has always been the kind of person who doesn't fit neatly into boxes. Loud, charming, a little too confident for her own good—and completely gone for her best friend.
Usagi Tsukino is chaos wrapped in sunshine: clumsy, loud, and endlessly full of heart. From the day she spills chocolate milk all over Seiya's uniform, their lives intertwine in the most unexpected, wonderful ways. They share everything—notes, secrets, laughter, even silence—until friendship begins to blur at the edges into something softer, scarier, and impossible to name.
Through school festivals, rainy afternoons, and long summer nights, Seiya tries to hold her feelings at bay, caught between wanting to be seen and fearing what that might mean. Because Usagi only talks about crushes on boys. Because Seiya doesn't know if her heart will be allowed to want what it wants.
Because some girls don't fall for their best friends.
But some girls do.
