Hikari's the kind of protagonist who makes you believe in her dream before she believes in it herself. The show stacks romance, gymnastics, and genuine friendship drama without ever feeling scattered, and it lets multiple women want the same guy without turning them into rivals. It's an 80s gem that remembers the point: watching someone you care about get better at something is its own kind of love story.
Hikari chases a dream forged in admiration: to become a rhythmic gymnastics champion like her idol, Diliana Gueorguiva. She is far from the best gymnast at her school, but she keeps working through her setbacks and, with support from Takaaki Oiishi, the school's top male gymnast, she wins a spot on the rhythmic gymnastics team. Along the way she falls for him. Shiina, the strongest gymnast in the whole school, loves Oiishi too, and the two girls become both friends and rivals, in the sport and for his heart. Hikari's feelings are further tangled by Mao Natsukawa, a childhood friend who fronts the band Mr. D, writes the music for her routines, and has loved her since they were young. When a women's gymnastics champion visits, Hikari starts to long for a place at a world youth championship.
