One is a girl who has no sense of existence and is considered autistic by everyone - Hayakawa Asaka;
One is Tezuka Kunimitsu, the pillar of the Seigaku Tennis Club and the dream prince charming of all the girls in the school;
The two people were obviously not in the same world and should not have any relationship and could not be weighed on the same scale, but unexpectedly they became sweet lovers.
Who knows, the unforgettable relationship between them,
The girl's farewell without saying goodbye, the boy's heart-breaking pain,
The distance I never understood, the world I never believed,
When the bell rings, will you return to the original place as promised...
