The Promise of Raindrop Proportion

In a small town during the rainy season, rain can remember everything. In the summer when he was seven years old, Shun Morita's memory was completely erased. Until he met Chiyo Fujisawa in the rain - a girl who only existed in the rainy season, with forty-three black beads strung on her wrist. "Memory is like the beach after the tide recedes, there will always be something left behind." Two people with incomplete memories search for the forgotten truth in the raindrops. The moment Qian Yang's hand passed through his body, the secret of the tsunami eighteen years ago fell like raindrops.
