Until the Last Rainfall

Three years ago, Kai Moriyama survived the night his sister didn't.
A single push in the rain.
A single choice.
A single memory he cannot fully recall.
Now he's back in the seaside town he ran from - back in the same high school, back in the same streets, back in the shadow of a storm that never really ended.
But something waits for him when the sky turns dark.
A girl who appears only in the rain.
A voice that knows what he refuses to remember.
A presence no one else can see.
As childhood friends drift closer and secrets begin to surface, Kai is forced to confront the truth behind that night - and the fragile line between grief and love, memory and illusion, the living and the lost.
Because some promises don't disappear.
They fall.
Again and again.
Until the last rainfall.
