Yui Yamada, a timid girl who enjoys tending to her school's garden, falls in love with the athletic Tomoka Kase. The two eventually begin dating, and the story follows the pair as they face various challenges in their relationship.

• Yui Yamada: • A shy and timid girl who is part of her school's greenery committee and loves weeding the school grounds. She falls in love with Kase and soon begins dating her, although she often gets paranoid over things. After graduating from high school, she goes to Tokyo with Kase to study horticulture at a women's university. • Tomoka Kase: • A boyish looking girl who is part of her school's track and field club and has exceedingly good athletic skill, often racing in tournaments. She takes an interest in Yamada and soon starts dating her, although she can sometimes act a little perverted. After graduating from high school, she goes to a sport university in Tokyo. • Mikawa: • Yamada's best friend, nicknamed Mikawacchi, who is initially suspicious of her relationship with Kase, having heard various rumors about her. She is quite boisterous but can't stand the sight of blood. After graduation, she goes to a college in Tokyo to study tourism. • Akane Inoue • Minako Kotobuki • A graduate who was in the same track club as Kase and attends the same university Kase later attends. As a result of rumors, she is long believed by Yamada to be Kase's ex-girlfriend, although this is eventually proven to be false.
