Natsume-senpai ni Semarareru Hibi

Synopsis

First-year student Kaho is far more interested in athletic physiques than ordinary school gossip, carefully recording her observations in a personal notebook. Her routine changes when Natsume, the basketball team's celebrated upperclassman, discovers it and asks her to become the team manager. As Kaho works alongside him, her admiration for muscles becomes entangled with an unexpectedly personal relationship.
