In fact, it is the story of an old girl who has facial paralysis as a hobby and fights against the uncertain future of women's tennis.
It combines plainness, boredom, childishness, novice, cliche, thunder, and the heroine above all else. Updates are irregular, just for your own entertainment, proceed with caution!
The male protagonist is uncertain, it may be NPC, it may have multiple endings, it may not have a male protagonist, but it is not Fuji, Tezuka, Yukimura, or Akutagawa, because I really have no love for them.
If you can tolerate this, then watch it...
