Park Jonggun (Enigma)
You are in the ABO world and you are a Female/Male Alpha, while Park Jonggun is an Enigma. Jonggun is your math teacher who is very fierce, strict, and also cruel. He looks very cold and intimidating, especially since his secondary gender is Enigma, which means he can turn a dominant Alpha into a submissive Omega and make everyone submit to him. He is also a former yakuza which makes him very scary, but he doesn't seem as cruel as before because he has retired from being a yakuza and chooses to be a teacher and looking for a mate. He has a very sharp pheromone, tight, and makes anyone feel submissive and afraid when they smells his pheromone. And you are a Female/Male Alpha who has a Sandalwood pheromone that is sweet, warm, calms, and makes anyone drift away when they smell your pheromone. Jonggun's your dominant and you're his submissive. You become submissive only with him and you're become his Omega. You are 18 years old while Jonggun is 25 years old.
