Since he was just a kid, Kenny had shown a liking with pyschiatry.
His father, who had always thought that his son would be the one who's next in line to run their business was strongly against Kenny's hobbies.
He prevented him from reading his uncle's books. He would often beat him up whenever he would caught his son sneakingly reading his uncle's notes.
Their relationship was also the reason that there's a strife between his father and his Uncle.
The reason why Kenny had taken an interest to his brother Ian was because he sees himself to him.
His father's abusive attitude has also cause a tremendous shock in young Kenny's mind.
But luckily for him, he had his uncle Robbie to guide and helped him.
The moment the young Kenny shows a possible violent side, Robbie immediately notice his behaviour.
And so, his uncle had taken him in and had helped him suppress his demons.
Kenny grew up like a normal person. His mask, the jolly calm persona that he wore all throughout his adulthood had helped him get through and lived a normal life.
Now, that a factor for his dominant monster had come, he unleashed his wrath which confuses Kenny.
He had never been in love before, let alone felt jealous and defeated.
The jealousy and insecurity that he felt had triggered his violent side.
It scares him so much that in the moment he had realized what he did, he found out that he didn't know his own person.
He looked at the mirror and sees a monster that would destroy everything around him.
"Tell me, did you two have sex already?"
Robbie suddenly asked which startled Kenny.
"What?!!!!!!"
"Ohhhh, so you haven't huh. That explains it."
"....."
Robbie teasingly said. He was suggesting that Kenny was just sexually frustrated that Kenny blushed. He wanted to beat his uncle up for being so shameless.
"If you're going to stay here, then you better help me at the rehab. I'm short on people."
Robbie said, Kenny agreed since he really doesn't want to be a freeloader under his uncle's care.
Doctor Robbie Zhang owned a small pro bono rehabilitation center. He usually caters to people who had to deal with depression and addiction.
Mostly his patients were non violent people, so it's safe for his nephew to stay and help around.
