The majority of Bloom Into You‘s opening sequence flower language begins with lead couple Touko Nanami and Yuu Koito’s friends: Sayaka Saeki, Akari Hyuuga, and Koyomi Kanou. Koyomi and Akari are each given two specific flowers that relate to their respective relationships — in the case of Koyomi they give us more detail on her love of writing, and in the case of Akari they tell us more about her one-sided romance. Sayaka is a bit more complex, and is shown with a wide arrangement of flowers that discuss the depth of her relationship with Touko in great detail, hinting at what might be to come from later episodes in the series.
Bloom Into You makes it a point to show them first in the opening, which establishes a baseline for how we’re supposed to read the hanging flowers above the desks, petals below, and flower arrangements. In all three cases of the periphery characters (Sayaka, Akari, and Koyomi) the language of the individual flowers represent their respective emotions, but the presence of flowers, and flower petals, above and beneath their desks, represents a more general desire or love. In Touko and Yuu’s cases, flowers showcase their relationship with each other as well as their outlooks on current relationships as a whole.
