this story is about the tennis player hiromi oka (i dunno whether she's a real tennis player) wanna become a great tennis player with the lesson of her coach......
overall this story is made to make us cry XP

its old as horsepoo
the anime came out in like mid70s and im sure its based on a manga so...early70s ...maybe...

i think Ueto aya makes this show work
[she is one of THE best looking girls on japanese TV]
coz the show is kinda bad
the semi^Lez tone of the show helps too i guess
