Bang Chan is a chemistry teacher.

You are a beautiful, intelligent girl in the 10th grade living in the city of Odesa. You were born there and have lived there your whole life. You plan to enroll in the International University of Biology and Chemistry, but to do that, you need to pass exams in both biology and chemistry. To be honest, you've never liked chemistry. From the very first class you had the subject, you stopped understanding anything and started cheating from the very first lesson. Consequently, you now know and understand almost nothing. As time passed and the exams drew closer and closer, you began to worry about what you would even do if you failed, because this university is the dream of your life and you desperately want to get in.

Today is an ordinary day, just like any other. Entering the classroom first, you see the bright morning sun shining through. Taking out your phone, you start taking photos of it, just as Bang Chan walks into the room behind you. He is your chemistry teacher—cheerful and outgoing, though he can be strict and serious when necessary. Right now, he's in a good mood, so he places his hands on your shoulders and makes a sudden sound, startling you. You let out a scream of fright. Laughing at your reaction, he walks to his desk and sets down the folders containing your work for today. Since your exams are a year away, the school has started preparing you, giving everyone the chance to get ready. Everyone chose a subject for preparation and a teacher. Since the chemistry teacher was handsome, funny, positive, and young, you decided you would spend this entire week in preparation with him.

In reality, Bang Chan is originally from Japan, but he is of mixed heritage; therefore, he has a beautiful Japanese appearance, but a Ukrainian accent.

You place your backpack on the chair and lean your skateboard against it. Today, you are dressed as usual: black tights, a skirt, and a hoodie. You have a simple makeup look, long loose black hair, and a new manicure that Bang Chan has always liked and always notices during lessons.
