"If you don't have a true love for volleyball, you'll never be strong."
This was the answer Sora Ichinose got from Ushijima Wakali after five years of one-sided competition.
Things to note:
1. BG, CP Uruwa, the female protagonist is one year older than the male protagonist
2. The heroine is awesome
3. Love is the main line, supplemented by sports.
4. Negative numbers, black holes, don't expect it
5. The idea comes from a dream of a friend
Concept: competition and love.
