Anonymous Noise - S01

Every day, a young girl in a mask stands by the beach and sings a nostalgic melody. When she was only a child, Nino Arisugawa went through two sudden and painful partings, and ever since, she has sung her songs to the ocean, bound by a promise she made with her two childhood friends: her first love, Momo Sakaki, and a boy who composed music, Kanade "Yuzu" Yuzuriha. The boys never met each other, but each promised that if Nino was ever separated from them, her voice would be the beacon to bring them together again. After six long years, fate has finally placed Nino, Momo, and Yuzu in the same high school. But time has changed many things in their lives. Nino keeps trying to fulfill her childhood promise with the boys, while Yuzu's old feelings for her resurface, and Momo goes to great lengths to prevent a reunion with Nino. Through music, will they be able to mend their friendship and overcome all the feelings tangled up in this complicated love triangle?
