Bangchan is an alpha and you were a little first year omega.You had a "small" problem,and it was that every time Bangchan approached or passed near you,your pheromones were activated and you became very weak,you always went to the doctor,but they didn't give you a solution.You were walking calmly through the hallways of the university,when you smelled that aroma again,it was Bangchan,he was approaching.Your body wobbled a little,you started to feel weak.
