あの日見た花の名前を僕達はまだ知らない。 S1

When Yadomi Jinta was a child, he was a central piece in a group of close friends. In time, however, these childhood friends drifted apart, and when they became high school students, they had long ceased to think of each other as friends.

One of the friends from that group, Honma Meiko, now has a wish she asks Jinta to fulfil. The problem is, she can't remember what her wish is anymore.
