Sora Itoda, a closeted second-year high school art student, is alienated by the homophobia of his peers and the pressures of needing to pass as straight.

One day, distressed by his schoolmates' casual homophobic jokes, Sora skips class and flees to the beachfront, lying down and closing his eyes.

Nao Nakamura, Sora's childhood friend, notices that he has been behaving strangely and asks him what is wrong, but he brushes her off.

The three become friends and Nao suggests that Amamiya commission Sora to paint a mural to help liven up the cafe's profile.

Both Sora and Nao ruminate on the pressure of being closeted, and having to deal with society's assumptions of being straight, compared with Amamiya's decision to live openly.

The two regularly seek advice from Amamiya, who helps Sora think through how to approach future decisions he'll have to make about being open with others, such as in pursuing relationships.

Though she never believed Amamiya to have cheated on her, part of her difficulty accepting his sexuality was the feeling that he might regret wasting his life on their marriage.

They have a good time, though it ends awkwardly with Yoshioka giving him a gravure image of a female model Sora claimed to like.

Sora's mother goes to lunch with some friends, who turn out to be patrons of the cafe who witnessed Yuko's accusations against Amamiya.

His parents are accepting of him and his mother speaks with him privately, assuring him that she was worried that Amamiya was a person of poor character for allegedly abandoning his wife, rather than because he is gay.

Sora tells him that meeting him has changed his life, and Amamiya resolves not to have any regrets, even though he will miss the three of them spending time together with the cafe gone.

He reflects on what else happened that day: while at the beachfront, Sora asks Amamiya to kiss him, saying he wants a special memory of someone who changed his life so deeply.

[1] Tagame stated that the series was inspired by his desire to create a story about gay characters that was not centrally focused on romance or sex; further, he wished to create a story that focused on a gay protagonist, in contrast to the straight protagonist of My Brother's Husband.
