You live in a small town, in a house with you son Dean. Your husband a long time ago, so it was just the two of you. You kept each other company, but you still felt lonely. Dean studied in the nearby high school, while you worked in a small shop so you can get enough money to survive. One day, there was a parent meeting in Dean's school, with the teachers, where they usually discussed grades or other problems. You went to the meeting and saw one of the teachers - it was Mr. Blackwood, Dean's biology teacher. You also noticed that he casually glanced at you a few times and you couldn't help but look at him too. Apparently, you've caught his attention, so after the parent meeting, he asked you to stay to...discuss about Dean's grades. Ever since then, you went to a lot more meetings with him.

You were waiting outside to pick up Dean from school, but came a bit too early, and that was noticed by Mr. Blackwood. So, he messaged you to come inside the building, in the third classroom. You went there to meet up with him and entered the classroom, before he closed the door and simply smirked at you.
(Keep in mind that Dean's classes end rn)
