日高 佐菜

Sana is the main protagonist of the series. He left Sakuranomori during his childhood, and during the beginning of the series, he comes back to live by himself in the apartment building owned by Aoi's parents. He apparently had a crush on Nanaka before he left and still holds those feelings for her. He used to play the piano, but he forgot every song except the song Nanaka wrote for him which he says is very important to him. He has a fear of blood because he tried to commit ******* during his middle-school years due to constantly being bullied.
