When they first met at the stairs, placed outside of the school, Tohko's first impression of Kakeru was "David". Despite it was the first time they met, Kakeru calls her by her first name. Kakeru is interested in Tohko due to her ability to see the future when they are together. It is unknown if Kakeru has any romantic feelings towards Tohko but there are hints that he may have developed some considering in Episode 6, he wondered if she was the one who was looking for since he keeps on hearing her voice. She responded with something similar, that she keeps on seeing him (when she sees the future). In episode 7, it is unclear if Tohko and Kakeru are dating, however, were seen holding hands in the beginning of the episode and going to the beach together later alone. Tohko made a glass bead bracelet for him to wear, which she gave to him at the beach. In episode 10 of the anime, Kakeru kisses Tohko. In episode 11, the two spend time together at the school, which they sleep in the art room, but Kakeru makes it back home early in the morning. Later in the episode, he tells her that his mother gave him the opportunity to travel around the world with her. He tells Tohko that he may be leaving with her, but she becomes angry with him, asking if he didn't have fun this summer with her and the rest of her friends. At Kakeru's house, Mrs. Okikura plays the piano for Tohko, because she asks her to. While she plays, Tohko hesitates to hold his hand, but he grabs it and squeezes it. They stay like that while she plays it and Touko begins to see a vision with the glass vase her family brought in as a present.
