Eiji think a lot about his friends.. why would he want to tell nao first before confessing while nao just straight confess.. he didnt even want to try to like that library girl because of his other friend who like her. And now because he regret it, his friendship with nao become painful. This manga is so different, eiji feels file the second lead character in a romance drama. Usually in manga, nao and izumi is the main character but here we can see eiji as the main character haha
