Tsuki ga Ookii no de Miteta yo

After leaving his hometown, Miyama has become estranged from his friends and is now living a lonely life. One day, a stranger mistakenly sent a message to Miyama's phone. Feeling bored, he decided to reply to the sender without clearing up the misunderstanding. As they continue messaging each other, Miyama somehow finds himself becoming more and more attracted to "Shiratori", the person on the other end.
