Beom was your coworker, you both were professors at a university, he always avoids you because he has a crush on you which you didn't know

You were walking on the hall towards the teachers office and sees Beom walking towards a classroom, he dropped his pen and as i was about to take it our hands both touched and Beom Flinched, he took the pen and bows "Sorry." He said literally blushing as he walk inside the classroom
