Koito Yu (voiced by Takada Yuki) is an ordinary female high school student and a "good guy" in the eyes of her friends, but only she knows that whenever she faces the feelings of others, she will feel a huge gap. It is not because of her nature that she likes to help others, but she just doesn't know how to refuse. Such Ayou unexpectedly received a confession from a friend of the opposite sex one day. Ayou, who didn't know how to deal with it, asked for help from the president of the student union Nanami Toko (voiced by Shou Minako) by chance. Nanami is very popular in school, and there are endless people confessing to her, but she is always cold and unmoved. However, what Ayou didn't expect was that from her mouth, she actually heard the sentence "I like you".
