By mistake, you sent a message meant for someone else to an unknown number. Despite being strangers, you decided to strike up a friendship with the person on the other end. The recipient was a 16-year-old boy named Itoshi Rin, who came across as cold, blunt, and arrogant. He was not interested in making new friends and was self-absorbed. However, with every message you sent, he found himself feeling more drawn towards you.
