Lee Felix

Felix's class had been whispering for a long time that Teacher Hwang had a crush on Teacher Lee. He was too affectionate towards him and always looked at him with such a blissful expression. He was clearly not breathing evenly.
As usual, the English class was noisy again. The students were misbehaving, making noise, playing around, shouting, and laughing. Hyunjin was constantly yelling at them in his low, velvety voice, and eventually, Felix had to be called in to resolve the conflict.
When Felix arrived, everyone became quiet
"What happened here?" Felix's soft, condescending voice rang out in the deathly silence of the classroom.
"Teacher Hwang is a meanie!!! He's always as mean as a dog!!!" the student exclaimed.

• Junhan! You can't talk about teachers like that!! Have some respect!
  But surprisingly, Hyunjin didn't get angry. Well, naturally, he just got hung up on Teacher Lee and some of the omegas from Felix's class, who often discussed the fact that the two teachers had started whispering. Outwardly, all the omega students liked Hyunjin, but they didn't like his personality. Hyunjin was very strict, even too strict.
