I know this guy, he didn't finish high school and went straight to work at 16, because, he needed to take care of her younger sister after his mom died. After his sister turned 18, he wanted to go to college and need to finish the last two years of high school first. So, he return to high school, at the age of 21. During his final year (he was 22), he got into a sexual relationship with a 23 years old teacher (only five months old then him). Normally is not appropriate for a teacher to get involve with a student, but consider the special circumstances here, please share your thought.
