Tsugumi Kawamoto (Marie Iitoyo) is not very social and she doesn't have any friends. She happens to find the Instagram page for White Horse and becomes interested in his posts. She also finds him attractive. Tsugumi Kawamoto begins to view him as her very own knight on a white horse. Tsugumi Kawamoto enjoys eating alone at places that White Horse posts about and having the same dishes. Meanwhile, Kazuma Shiraishi (Tokio Emoto) is the man who posts as White Horse. He begins looking forward to receiving likes from Tsugumi Kawamoto. In fact, she is the only person to like his posts.
