[Poison Gray (Matsuriuta)] Happy Sowing First-Year! [q91]

A boy's 'Sowing Plan for the Future' unfolds through evolving character profiles that chart his tomboy childhood friend Manami's transformation from a 95%-lewd-affinity innocent who thinks his camera function is neat, to a nude, sex-addicted companion with 119 encounters logged and her affinity maxed at 100%. Between sowing sessions, Shouta returns home to his doting young mother Yuka, a curvy single mom who greets him with 'Did you get to sow a lot today?' and rewards a productive day by spoiling him in ways well beyond maternal. A stat-sheet-driven growth story where heights climb, measurements tick upward, and that stubborn 0% fertilization probability only makes him try harder.
