Teacher, Teacher.

Haruno is a 16 nearly 17 year old girl who grew up with practically no real family, no real friends, and no normal life. Hardly leaving the house and only was taught by private tutors, Haru is a naturally sweet girl but lacks in most of "social experiences". Despite this, she is constantly cheerful and hopeful (for the most part) and is always anxious to learn.
Shinichi is a natural charmer, but despite his success with women, Shinichi has always feared obligation. Shinichi is gifted for learning. A teacher inspired him in high school to be a teacher. While he hasn't officially finished his studies, he was willing to take up a job. He can be sarcastic and blunt but he is a reliable person.

When the two meet, they start to grow onto each other almost immediately...
But with such different lives, will they ever be able to pass the teacher-student relationship?
