Despite his cold and arrogant appearance, Takara is one of the most popular guys in Fujimine High and often receives a number of confessions from the girls around him to which he shows little or no interest. One day as Takara and Amagi, a peer of his who he's barely had an interaction with, are assigned to weed the campus grounds, Amagi accidentally slips out his confession to Takara to which Takara surprisingly agrees to date Amagi. However, this supposed relationship between the two is off to a rocky start as Takara's apparent lack of affection and recognition for Amagi has left the latter feeling rather sad and confused.

Takara and Amagi are finally officially lovers. Amagi, who had savored the happiness of being able to be with him at all times, had a stimulating dream in which he was pressed by Takara, and was so embarrassed that he behaved unnaturally towards him. His adviser, Katori , also told him that "dreams are the manifestation of desires," which made him even more conscious.

In the face of their upcoming three-day holiday and with Amagi worried about how to spend it, Takara decides to invite him to come and stay over at his house, which leads to the couple's first overnight experience! Now that they finally have some time alone, what shy and silly things will they do as a couple?

Just after experiencing their first night together, Takara and Amagi seem to be more sure of their feelings for each other, and the interaction between the two at school has also increased a lot. However, one day after school, just as the two are going home together, Amagi suddenly bursts into tears….

As their relationship furthers, Amagi finds himself feeling increasingly perplexed about how he is supposed to get along with Takara. And just as he's beginning to feel uneasy from the pressure of it, Takara invites him out to a day trip and the two enjoy a happy and fulfilling date together. However, in the midst of their date, they unexpectedly spot some of their classmates and immediately run into hiding. Will the secret love birds ever be brave enough to take their relationship public?
