Haruto has never been afraid to say how he feels—especially when it comes to Kaori, the childhood friend who has always been by his side. To him, their future feels simple, almost certain.

But one Monsoon , Kaori begins to disappear from that future.

She stops coming to school. Stops replying to messages. And when she does appear, she avoids him—like he’s someone she shouldn’t get close to anymore.

Haruto doesn’t understand why.

Refusing to accept the growing distance between them, he chases after the truth Kaori is desperately trying to hide. Yet the closer he gets, the more he realizes that her silence isn’t rejection… but something far more painful.

Set against quiet rainy days and fading summer light, this is a story of unspoken love, fragile moments, and the kind of goodbye that arrives long before the end.
