## Plot

Naisho no Tsubomi tells the story of Tsubomi Tachibana, a fifth grader dealing with rather sensitive issues such as her mother's pregnancy, her first period and the strange feelings she has started to get when around boys. When she first met Daiki, she tends to blush a lot when she is around him, she does not know what that feeling is at first, but further into the story she then discovers that she, in fact, has fallen in love with Daiki.
Each volume tells the story of a different girl, always with the given name of Tsubomi and similar appearance. In each case the story deals with various issues the girl experiences with early adolescence, including physical matters such as menstruation and breast development, personal issues such as the first crush, and more uncommon but dangerous issues such as the risk of predation (this was not included in the anime). Each story also includes some source of candid advice and information to support the girl, such as the spirit of a future sibling (volume 1), an alien posing as a twin brother (volume 2), or even another self from a parallel universe (volume 5).

## Main characters
### Tsubomi Tachibana (立花 つぼみ, Tachibana Tsubomi)

    A fifth grader who deals with sensitive issues while growing up. She is worried about the people around her and tries hard to help them when they are in need. This leads to her trying to handle issues such as her first menstruation alone. Although Tsubomi is a responsible and helpful girl, she is naive in a sense that she does not understand many things around her. She is happy about her mother's pregnancy, as she is an only child and has always wanted a sibling.
    She is troubled about lot of things like the strange feelings that she has around Nemoto, the "indecent things" that her parents have done to make a baby, and her feelings towards Saya when she gets close to Nemoto. Tsubomi is shown to have feelings for Nemoto but does not quite know it herself at first. She later confesses to Nemoto, and the two become a couple.
