After experiencing betrayal from her old friends, Erine struggled to connect with people again. She spent almost two years in isolation, with only her siblings and cousin for company. One day, she came across her old friends. Feeling nervous after running into them, she searched for someone to talk to and discover an old account named Jance Takahashi. She started sharing her stories and thoughts there, even though she never received any replies. It was only later that she found out the account she thought was her private diary actually belonged to Adriel Jance, a classmate and friend of her cousin Raika.
