The only thing that a high school writer can open his heart is an older man, "Altair," whom he met online.
Through his hobby of observing celestial bodies, he enjoys exchanging e-mails in a calm manner.
After the graduation ceremony, the writer, who was severely hurt by his friend's words, met for the first time with a Altair who rushed to his house and became even more attracted to his personality, but as he didn't even know his real name, his contact with him was cut off.
A few months later, was his fiancé whom his sister brought with him? Is that Altair?
