Starting from the start, I will voting for Hana Kimi Japan Ver.

Hana Kimi Series is about
Horikita plays the protagonist Ashiya Mizuki, a Japanese girl in the
U.S. who one day sees the young athlete Sano Izumi (Oguri) compete in
the high jump on television. She begins to idolize him, and decides to
move to Japan to attend the same school as him. However, Izumi goes to
an all-boys school, so Mizuki disguises herself as a boy to achieve her
dream of being with her idol and to make her idol to jump again
