Naito Hayato died of illness in his previous life, then was reborn as a tennis player who thought he was perfectly ordinary.
It wasn't until he entered fourth grade and attended his first gender education class that he suddenly realized this world seemed to divide people into boys and girls only until sixth grade. Most people differentiated into alphas, betas, or omegas during the summer break before moving on to middle school.
What was ABO? He had just acquired knowledge he'd never encountered before.
His childhood friend and doubles partner said, "Hayato really is an idiot, huh? You don't even know that?"
After the Kansai Junior Doubles Tournament, the former partners had a fierce argument, and their partnership fell apart.
Naito moved to Tokyo with his parents and enrolled at Hyotei Academy.
From then on, a proper Kansai boy began his journey toward the national stage.
Little scene:
Naito greatly admired the captains of Seigaku and the vice-captain of Rikkai, which always left his senior worrying that one day he might suddenly turn into Hyotei's Tezuka or Hyotei's Sanada.
Senior: Please, whatever happens, don't let that happen!!!
A few things to know:
# The male lead is one year below Atobe
# The male lead can't smell pheromones, so he can't tell the difference between ABOS
# There will be one-sided crushes on the male lead, all youthful and innocent
# There will be a golden finger, but it won't be too overpowered
# Original settings and out-of-character portrayals warning
Theme: Passion is the defining tone of youth.
